Summary of changes from v2.5.39 to v2.5.40
============================================
<rmk@flint.arm.linux.org.uk>
[ARM] Add Thumb syscall stubs and drop gcc asm workarounds.
Add support for Thumb stubs (for klibc.)
We drop a work-around for early gcc versions where register
variables didn't work as expected; this allows us to get rid
of several lines of ASM per syscall.
<rmk@flint.arm.linux.org.uk>
[ARM] Move PHYS_TO_NID() to asm/memory.h
When CONFIG_DISCONTIGMEM=n, we define PHYS_TO_NID(x) to zero in each
architecture specific file. This cset moves it into the generic
ARM code.
<rmk@flint.arm.linux.org.uk>
[ARM] Put back the CPU MM context switch avoidence test.
On context switch, when the MM hasn't changed, we can avoid calling
the architecture specific area.
<rmk@flint.arm.linux.org.uk>
[ARM] Thumb fixes
This cset fixes a set of problems discovered while developing KLIBC
with Thumb support. We now allow pure Thumb executables, and prevent
such executables from being run on non-Thumb code aware CPUs.
We also fix a bug in the fixup of Thumb late aborts which rather
messed things up.
<rmk@flint.arm.linux.org.uk>
[ARM] Always decend into compressed and bootp subdirectories.
Make was missing the need to rebuild the kernel decompressor when
files in arch/arm/boot/compressed are changed. This is because
make believes that the object contained within is up to date
(because it doesn't know any better.) This cset always forces us
to decend into these two directories if the objects inside these
are required.
<rmk@flint.arm.linux.org.uk>
[ARM] Make "bootp" Image generation know that the zImage is now PIC.
Since a bootp image contains a zImage and an initrd (or maybe later
an initramfs) image, and the zImage is now PIC, we don't have to
copy the zImage to a specific address before calling it. We just
call it where it got loaded into memory and let it sort itself out.
<rmk@flint.arm.linux.org.uk>
[ARM] Fix XScale "feature"
XScale does not guarantee that CPU control register writes complete
their side effects immediately. In fact, Intel give sample code to
demonstrate a way to ensure that the effect of the write has occurred.
This is specific to Xscale, but the fix should work on any ARM CPU.
We therefore jump through the loops in "spirit" but not necessarily
in exactly the same way as the sample code.
<rmk@flint.arm.linux.org.uk>
Since irq_exit() now deals with softirqs, irq_enter and irq_exit
must be located at the top level of the interrupt handler.
<rmk@flint.arm.linux.org.uk>
[ARM] Remove old AMBA KMI driver information.
We now have an input layer driver for the keyboard/mouse, so this
isn't required.
<ch@hpl.hp.com>
[ARM PATCH] 1255/1: [PATCH] SA-1111 PCI support for USB
Fixes several oopsen in the SA-1111 "fake" PCI support
Complete re-write of the SA-1111 DMA bug "bounce buffer" workaround.
Merge latest drivers/pci/pool.c into mach-sa1100/pcipool.c (pool
allocation debugging follows CONFIG_DEBUG_SLAB a la drivers/pci/pool.c)
/arch/arm/mach-sa1100/pcipool.h can be deleted
(unrelated: /arch/arm/mach-sa1100/sa1111-ohci.c can be deleted)
Applies to 2.5.30-rmk1. Should be back ported to 2.4 as the existing
SA-1111 bounce buffer code is broken.
(This patch is *required* for the OHCI HCD driver that is part of 2.5.21+.)
<rmk@flint.arm.linux.org.uk>
[ARM] Fix up initcall ordering
ARM machine support gets initialised too late in the initialisation
order and can cause some things to unexpectedly fail. Fix the
ordering of these initcalls by placing them in the core and arch
initcall sections.
<rmk@flint.arm.linux.org.uk>
[ARM] Provide hook for FP emulators to know when a new thread is created
This allows FP emulators to take their FP initialisation out of the
hot path.
<rmk@flint.arm.linux.org.uk>
[ARM] Move machine config questions into machine class subdirs
This cset moves a fair amount of per-machine questions into their
relevant machine class subdirectory, making arch/arm/config.in
easier on the eyes.
<jeffs@accelent.com>
[ARM PATCH] 1238/1: Accelent PXA IDP config cleanups
This patch brings support for the PXA-IDP up to 2.5.30, plus adds
support in head.S for low level serial debugging support.
<rmk@flint.arm.linux.org.uk>
[ARM] Update nwfpe to use new fp_init hook.
Take FPA11_CheckInit out of the hot path, and use the fp_init hook
instead.
<davem@nuts.ninka.net>

<davem@nuts.ninka.net>
arch/sparc64/defconfig: Update.
<jdike@uml.karaya.com>
Bumped EXTRAVERSION for the 2.4 fixes and highmem support.
<jdike@uml.karaya.com>
Added highmem support.
The UML initialization code marks memory that doesn't fit in the
kernel's address space as highmem, and later sets up the UML data
structures for it, and frees that memory to the mm system as highmem.
<davem@nuts.ninka.net>
sound/sparc/cs4231.c: Fix probing bugs.
- Only check compatible OBP property if ebus device
name is audio
- Fix ebus device ioremap args
- Accept ID 0x0c as well as 0x0a
- Fix explicit inb, replace with __cs4231_readb
- Do not forget to set CS4231_FLAG_EBUS

<acme@conectiva.com.br>
[X25] fix thinko in x25_facilities
<nico@cam.org>
[ARM PATCH] 1302/1: ARMv5 optimized findbit
Question: is there any reason to do all this with byte access rather than
word access besides alignment issues? Word access would be much faster.
<sam@mars.ravnborg.org>
Remove unused clean: target in various makefiles
Simple cleanup, kbuild does not use distributed clean target, so bettet get rid of them.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: cleanup ISDN net / ioctl code
Try to convert the setup of network interfaces into something readable.
In particular, use dummy inline functions to get rid of
#ifdef CONFIG_ISDN_* spread all over the place everywhere and separate
stuff into smaller functions.
<rmk@flint.arm.linux.org.uk>
[ARM] Don't continue to process pending interrupts after disable_irq()
This solves a problem whereby the generic interrupt code repeatedly
called an interrupt handler, even though the interrupt handler had
called disable_irq().
<rmk@flint.arm.linux.org.uk>
[ARM] Parse initrd information early
We need the initrd location before the normal command line parsing
occurs so we can reserve the right bits of memory, and not double-
free the initrd during userspace boot.
<rmk@flint.arm.linux.org.uk>
[ARM] Add DC21285 decompressor debug support
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Move CISCO HDLCK protocol into separate file
SyncPPP and X25 are already (kind of) separated, so do the same for CISCO
HDLCK.
<yoshfuji@linux-ipv6.org>
net/ipv6/addrconf.c: Refine IPv6 Address Validation Timer.
<torvalds@home.transmeta.com>
Remove more tmp-file on clean (introduced with kallsyms)
<kai@tp1.ruhr-uni-bochum.de>
ISDN: More cleanup to isdn_net.c (X.25 / PPP)
Again, instead of having stuff cluttered all over isdn_net.c, put
it into the files where it belongs and get rid of the
#ifdef CONFIG_ISDN_X25 / CONFIG_ISDN_PPP by using dummy stubs if
necessary.
Same thing for CONFIG_ISDN_PPP.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Move net_device setup to a type-specific method
isdn_net handles all kind of interfaces, e.g. raw IP, ethernet over ISDN,
PPP - this is a cleanup making the setup of a net_device specific to the
type of interface.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: 'ethernet over ISDN' cleanups
<kai@tp1.ruhr-uni-bochum.de>
ISDN: net_device->header for CISCO HDLC
Break the CISCO specific part out of the generic isdn_net_header()
and move it to the CISCO code.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: net_device->header for syncPPP and UI HDLC
Break syncPPP and UI HDLC specific parts out of isdn_net_header()
and move it to more appropriate places.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: net_device->header for IPTYP
<kai@tp1.ruhr-uni-bochum.de>
ISDN: separate out 'ethernet over ISDN' receive function
First step in splitting isdn_net_receive into type specific functions.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: separate out IPTYP receive function
Another step in splitting isdn_net_receive into type specific functions.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: separate out RAWIP receive function

<kai@tp1.ruhr-uni-bochum.de>
ISDN: separate out CISCO HDLC receive function
Another step in splitting isdn_net_receive into type specific functions.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: separate out IPTYP receive function
Another step in splitting isdn_net_receive into type specific functions.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: finish separating out receive functions
Use the same form for the already existing PPP / X.25 receive functions
as for all the other ones, + small fixes.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use a function pointer for type-specific receive
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use a function pointer for type-specific connected() callback
Again, instead of a switch statement, just use a callback.
<acme@conectiva.com.br>
o LLC: remove unused list_head from llc_opt & use rw_lock_init for rwlocks
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use a function pointer for type-specific disconnected() callback
Again, instead of a switch statement, just use a callback.
<acme@conectiva.com.br>
o X25: Simplify ioctl code, CodingStyle cleanups
<acme@conectiva.com.br>
o X25: use refcounts and protect x25_route list
Also rename untypedefed x25_cb, renaming it to x25_opt, to make
it look like the other protocols.
Added some kerneldoc comments.
<acme@conectiva.com.br>
o LLC: rename llc_sock.c to af_llc.c
To make it look like the other protocols.
<yoshfuji@linux-ipv6.org>
net/ipv6/ndisc.c: Add missing credits.
<jdike@uml.karaya.com>

<jdike@uml.karaya.com>
Missed a change to fixmap.h in the highmem update.
<achirica@ttd.net>
airo wireless net drvr: add Cisco MIC support
Conditionally enabled when out-of-tree, but open source, crypto lib
is present.
<edward_peng@dlink.com.tw>
update sundance driver to support building on older kernel:
conditionally include crc32.h, ethtool.h, mii.h, and compat.h
if built outside the stock 2.4.x kernel.
<acme@conectiva.com.br>
o X25: use refcnts and protect x25_neigh structs and list

<acme@conectiva.com.br>
o X25: protect x25 sockets and list with refcnt and rwlock
<torvalds@home.transmeta.com>

* update all callers (just 8139cp, for now)
<acme@conectiva.com.br>
o X25: x25_wait_for_{data,connection_establishemnt} and the death of the last cli/sti pair in X.25
<akpm@digeo.com>
[PATCH] Fix uninitialized swapper_space lists
<kai@tp1.ruhr-uni-bochum.de>
ISDN: inline function for testing if interface is bound
Put the test for lp->flags & ISDN_NET_CONNECTED into an inline
function called isdn_net_bound(), which more accurately names what
we are testing for, i.e. the interface being bound to a hardware
ISDN channel, which however is not necessarily online yet.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Put slot index of reserved channel into ->exclusive
We will need the index of the channel we reserved later, so override
the meaning of ->exclusive.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: exclusive handling in isdn_net_force_dial_lp()
When using exclusive mode, we already reserved our channel
at the time that mode was set, so no need to get a free channel
in this case.
Also, indent cleanups to isdn_net_start_xmit().
<jgarzik@mandrakesoft.com>
[net drivers] Rename MII lib API member, s/duplex_lock/force_media/,
and update all drivers that reference this struct member.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Share code for initiating dial out
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use net/ethernet/eth.c eth_rebuild_header()
No need to duplicate that function privately.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Remove ISDN_NET_CONNECTED flags
The same information is present as (->isdn_slot >= 0), so don't
duplicate it (and risk it getting out of sync)
<acme@conectiva.com.br>
o LAPB: use refcounts and rwlock to protect lapb_cb and list
Also some CodingStyle code reformatting.
Ah, killed the typedef for lapb_cb.
<jgarzik@mandrakesoft.com>
Add helper function generic_mii_ioctl to MII lib, use it in 8139cp net drvr
<kai@tp1.ruhr-uni-bochum.de>
ISDN: unclutter isdn_net_find_icall()
The method to find out if an incoming call is addressed to
any of the ISDN network interfaces is horrible. A bit of splitting
and dropping the swap channels if exclusive logic makes it a bit
better at least.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Introduce generic bind/unbind callbacks
PPP wants callbacks at the time a connection between ISDN channel
and network interface is established, i.e. before dialing to
avoid dialing when no ipppd is present, so use generic
bind/unbind callbacks.
<yoshfuji@linux-ipv6.org>
net/ipv6/ip6_fib.c: Default route support on router.
<jgarzik@mandrakesoft.com>
Use new MII lib helper generic_mii_ioctl in several net drivers:
8139too, epic100, fealnx, sundance and via-rhine.
In the process, several of these net drivers gained MII ioctl
locking fixes simply by virtue of being brought in line with
standardized code.
<jgarzik@mandrakesoft.com>
[net drivers] Remove 'dev' argument from generic_mii_ioctl helper
<jgarzik@mandrakesoft.com>
[net drivers] add optional duplex-changed arg to generic_mii_ioctl helper
<davem@nuts.ninka.net>
[SPARC64]: Rework all EBUS DMA support.
- Add EBUS DMA layer so the same code does not need to
be debugged/duplicated several times.
- Convert Parport/Floppy/CS4231 to use new EBUS DMA layer.
<jgarzik@mandrakesoft.com>
[net drivers] update hamachi.c and starfire.c to use MII lib
<zaitcev@redhat.com>
[sparc]: defconfig update
<acme@conectiva.com.br>
o lapbether: get rid of cli/sti, use refcnts for devs, etc
<rmk@flint.arm.linux.org.uk>
[ARM] 2.5.34 update
Update for changes in mainline 2.5.3[01234].
<rmk@flint.arm.linux.org.uk>
[ARM] Unify integer register usage passed into FP module.
This allows the FP module to perform some extra optimisations.
<gilbertd@treblig.org>
[ARM PATCH] 1257/1: Helpful comment in stat.h
Hi,
For reasons of great complexity I found out the hard way that the
kernel must (and does) zero the pad sections in the stat structures.
Here is a comment that states this for the next person who needs to
know.
<gilbertd@treblig.org>
[ARM PATCH] 1260/1: Fix comment in nwfpe
Hi,
I believe the comment in the nwfpe fpopcodes is slightly wrong -
although a 2nd pair of eyes on this would be a good idea.
<rmk@flint.arm.linux.org.uk>
[ARM] NWFPE updates for new entry conditions.
<rmk@flint.arm.linux.org.uk>
[ARM] Remove keyboard.h includes and some generic ARM keyboard bits.
This keeps ARM in line with the continued transition to the input
layer.
<mingo@elte.hu>
[PATCH] sigfix-2.5.39-A1
This fixes the bug reported by David Mosberger, force_sig_info() dropped
the siginfo structure, which broke things like SIGFPU or alignment-error
exceptions. This bug was introduced by the threading signal changes.
(The patch also fixes signal declaration whitespaces in sched.h.)
<mingo@elte.hu>
[PATCH] futex-fix-2.5.39-A1
This fixes one more race left in the new futex hashing code, which
triggers if a futex waiter gets a signal after it has been woken up but
before it actually wakes up.
<mingo@elte.hu>
[PATCH] signal delivery to thread groups bugfix
Fix thread group signal sending
<mingo@elte.hu>
[PATCH] thread-group SIGSTOP handling
Fix thread-group SIGSTOP handling - the SIGSTOP notification was not
propagated to the parent of the thread group leader. Now Ctrl-Z-ing of
thread groups works again.
<mingo@elte.hu>
[PATCH] atomic-thread-signals
Avoid racing on signal delivery with thread signal blocking in thread
groups.
The method to do this is to eliminate the per-thread sigmask_lock, and
use the per-group (per 'process') siglock for all signal related
activities. This immensely simplified some of the locking interactions
within signal.c, and enabled the fixing of the above category of signal
delivery races.
This became possible due to the former thread-signal patch, which made
siglock an irq-safe thing. (it used to be a process-context-only
spinlock.) And this is even a speedup for non-threaded applications:
only one lock is used.
I fixed all places within the kernel except the non-x86 arch sections.
Even for them the transition is very straightforward, in almost every
case the following is sufficient in arch/*/kernel/signal.c:
:1,$s/->sigmask_lock/->sig->siglock/g
<mingo@elte.hu>
[PATCH] smptimers, old BH removal, tq-cleanup
This is the smptimers patch plus the removal of old BHs and a rewrite of
task-queue handling.
Basically with the removal of TIMER_BH i think the time is right to get
rid of old BHs forever, and to do a massive cleanup of all related
fields. The following five basic 'execution context' abstractions are
supported by the kernel:
- hardirq
- softirq
- tasklet
- keventd-driven task-queues
- process contexts
I've done the following cleanups/simplifications to task-queues:
- removed the ability to define your own task-queue, what can be done is
to schedule_task() a given task to keventd, and to flush all pending
tasks.
This is actually a quite easy transition, since 90% of all task-queue
users in the kernel used BH_IMMEDIATE - which is very similar in
functionality to keventd.
I believe task-queues should not be removed from the kernel altogether.
It's true that they were written as a candidate replacement for BHs
originally, but they do make sense in a different way: it's perhaps the
easiest interface to do deferred processing from IRQ context, in
performance-uncritical code areas. They are easier to use than
tasklets.
code that cares about performance should convert to tasklets - as the
timer code and the serial subsystem has done already. For extreme
performance softirqs should be used - the net subsystem does this.
and we can do this for 2.6 - there are only a couple of areas left after
fixing all the BH_IMMEDIATE places.
i have moved all the taskqueue handling code into kernel/context.c, and
only kept the basic 'queue a task' definitions in include/linux/tqueue.h.
I've converted three of the most commonly used BH_IMMEDIATE users:
tty_io.c, floppy.c and random.c. [random.c might need more thought
though.]
i've also cleaned up kernel/timer.c over that of the stock smptimers
patch: privatized the timer-vec definitions (nothing needs it,
init_timer() used it mistakenly) and cleaned up the code. Plus i've moved
some code around that does not belong into timer.c, and within timer.c
i've organized data and functions along functionality and further
separated the base timer code from the NTP bits.
net_bh_lock: i have removed it, since it would synchronize to nothing. The
old protocol handlers should still run on UP, and on SMP the kernel prints
a warning upon use. Alexey, is this approach fine with you?
scalable timers: i've further improved the patch ported to 2.5 by wli and
Dipankar. There is only one pending issue i can see, the question of
whether to migrate timers in mod_timer() or not. I'm quite convinced that
they should be migrated, but i might be wrong. It's a 10 lines change to
switch between migrating and non-migrating timers, we can do performance
tests later on. The current, more complex migration code is pretty fast
and has been stable under extremely high networking loads in the past 2
years, so we can immediately switch to the simpler variant if someone
proves it improves performance. (I'd say if non-migrating timers improve
Apache performance on one of the bigger NUMA boxes then the point is
proven, no further though will be needed.)

[ARM PATCH] 1293/1: fix to the ARM optimized strchr()
Two bugs here:
1) The return value of strchr("foo",0) should be the start address of
"foo" + 3, not NULL.
2) Since the second argument for strchr() is defined as an int, some
characters such as 'é' might validly end up to be the value -23 due to
signedness issues. Corectly handle those.

kbuild: Make scripts/Configure follow the definition of 'int'
Currently, scripts/Configure has code for the 'int' verb to take a
min/max. This violates the spec described in
Documentation/kbuild/config-language.txt. It also requires that if a
default is outside of +/- 10,000,000 that defaults be provided, or
'config' and 'oldconfig' will get stuck. The following removes the
support for a min/max from scripts/Configure.

ISDN: Introduce generic init/cleanup callbacks
X25 needs notification when encapsulation is set to X25 and when
it is changed to something else again, so let's have some callbacks
for init/cleanup.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Use ether_setup() for ethernet over ISDN only
The ->init() callback can be used for calling ether_setup() in case
of encapsulation "ISDN over ethernet", for the other cases it does not
make sense anyway.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Add close()/open() callbacks to ISDN net interface implementation
X25 needs notification if an interface is brought up or down, and
ethernet over ISDN creates a fake MAC address at open time, so put this
into appropriate callbacks as well.
<kai@tp1.ruhr-uni-bochum.de>
ISDN: Move "name" member from isdn_net_local to isdn_net_dev
This is the first step of a long series moving members between
isdn_net_local and isdn_net_dev.
Today, a one-to-one relationship between these both structures exist, so
it does not really matter where the members live. However, the goal
is to get a correspondence like
net_device -> isdn_net_local -> master isdn_net_device
|
slave isdn_net_device
|
slave isdn_net_device
where more than one isdn_net_device can exist per actual net_device,
due to channel bundling.

it doesn't affect "normal" users.

[PATCH] move_one_page kmap atomicity fix
move_one_page() is calling alloc_one_pte_map() while holding an atomic
kmap for the source pte's page. But alloc_one_pte_map() can sleep in
the page allocator.
So change move_one_page() to take a peek at the destination pagetables
to work out whether the alloc_one_pte_map() will need to perform page
allocation. If so, drop the atomic kmap and retake it after allocating
the pte.

[PATCH] remove GFP_NFS

<akpm@digeo.com>
[PATCH] add /proc/buddyinfo
From David Hansen, Bill Irwin, Martin Bligh.
"It's easier to cat /proc/buddyinfo than to beg users to press
shift-scrolllock on a machine millions of miles away. Order 1 and 2
memory allocations are common. Memory fragmentation is a problem
under some workloads, and this is a useful tool for helping diagnose
these problems."
The following patch exports some information about the buddy allocator.
Each column of numbers represents the number of pages of that order
which are available. In this case, there are 5 chunks of
2^2*PAGE_SIZE available in ZONE_DMA, and 101 chunks of 2^4*PAGE_SIZE
availble in ZONE_NORMAL, etc... This information can give you a good
idea about how fragmented memory is and give you a clue as to how big
an area you can safely allocate.
Node 0, zone DMA 0 4 5 4 4 3 ...
Node 0, zone Normal 1 0 0 1 101 8 ...
Node 0, zone HighMem 2 0 0 1 1 0 ...

[PATCH] per-node kswapd instances
Patch from David Hansen.
Start one kswapd instance for each NUMA node. That kswapd instance
only works against the pages which are local to that node.
We need to bind that kswapd to that node's CPU set, but the
infrastructure for this is not yet in place.
<akpm@digeo.com>
[PATCH] in-kernel topology API
From Matthew Dobson <colpatch@us.ibm.com>
"This patch adds a 'simple' in-kernel topology API. This API allows
for three primary topology elements: CPUs, memory blocks, and nodes.
The API allows for the discovery of which CPUs/Memory Blocks reside on
which nodes, and vice versa. Also implemented is a macro to get a
bitmask of CPUs on a particular node. This API is platform neutral."
We need this API for per-node-kswapd - without it there is no means by
which each kswapd can be bound to its node's CPUs. And we rather need
per-node-kswapd...
The patch also uses the new API to bind each kswapd instance to its
node's CPUs
<akpm@digeo.com>
[PATCH] topology API updates
From Matthew Dobson.
Leaves any functions which architectures haven't defined as undefined,
rather than using non-NUMA functions where users would expect
NUMA-functions.
This will cause compilation errors if someone tries to use an undefined
function, hopefully causing them to actually define those functions.
Also removes lingering topology-like macros that aren't being used, and
a couple typo fixes.

[PATCH] use fff/ffff/fffffff instead of ff8/fff8/ffffff8 for EOF of FAT
On FAT12, the current FAT driver recognizes 0xff8-0xfff as EOF, and it
writes in 0xff8 as EOF. This is right behavior. However, the firmware
of some MP3-Players recognize only 0xfff (standard EOF which Micorsoft
uses) as EOF.
So, we write 0xfff instead of 0xff8 as EOF, until the reason we need
values other than standard EOF is found.

[PATCH] sigfix-2.5.39-D0, BK-curr
This fixes a procfs crash noticed by Anton Blanchard.
The procfs code can have a reference even to an already exited task, so
it needs to follow special rules accessing p->sig. The atomic-signals
patch made this bug happen at a much higher frequency, but procfs i
believe was buggy ever since, it potentially used the freed signal
structure - which just did not result in a crash like it does today.
The proper fix is to take the tasklist read-lock in
collect_sigign_sigcatch(), this excludes __exit_sighand() freeing the
signal structure prematurely.

[PATCH] request_irq() use GFP_ATOMIC
The might_sleep() thing caught ide, which calls request_irq() with a
lock held. It can be argued that this is a bad thing, however I think it
can also validly be argued that requesting an irq should not be a
blocking operation. This might even remove some driver bugs where usage
count is not incremented during init...
It can also be argued, that the very first irq requests cannot be
blocking for io anyways, for good reason :-)

[PATCH] make loop set right queue restrictions
This makes loop honor the queue restrictions by basically stacking all
of those, and mirroring the merge_bvec_fn() on the target queue. It also
switches loop to use per-loop device queues, since that is the only sane
way to do this from a performance POV. Also, in principle I find it to
be much nicer if every distinct block device has its own queue.

[PATCH] raid5 BIO_UPTODATE set

[PATCH] get_gendisk() prototype change
get_gendisk() now takes dev_t (instead of kdev_t) and gets an additional
argument - int *part. Set to 0 for non-partitioned, partition number
for partititoned. Callers updated. Yes, I hate passing return values
that way ;-/ We need that since old "minor(dev) - disk->first_minor"
doesn't work for stuff with non-trivial numbers (e.g. floppy) and
get_gendisk() really has to return both gendisk and partition number.
Fortunately, amount of callers of gendisk() is about to drop RSN big way...

[PATCH] alloc_disk/put_disk
Beginning of proper refcounting. New helpers introduced, several drivers
switched to using them for dynamic allocation of gendisks. Once everything
is switched (and that will be way easier than per-drive gendisks series)
we will be able to add sane reference counts on gendisk, at which point
we can safely put pointer to gendisk in struct block_device / struct request
and we had pretty much won - from that point it's pretty straightforward
crapectomy in drivers.

[PATCH] cpufreq crashes on P4
In two drivers a wrong size of memory was allocated for cpufreq_driver: as
it must include NR_CPUS times a struct cpufreq_policy (and not struct
cpufreq_freqs). Thanks to Petr Vandrovec for this patch.

[ARM] sa1100fb updates
Update sa1100fb for recent fbcon changes, and move stork LCD power
handling into machine specific file.
<akpm@zip.com.au>
scsi_initialise_merge_fn() will only set highio if ->type == TYPE_DISK.
But it's called from scsi_add_lun()->scsi_alloc_sdev() before the type
is known. The type is -1 all the time in scsi_initialise_merge_fn()
and scsi always bounces.
This patch makes it do the right thing - just enable block-highmem for
all scsi devices.
Jens had this to say:
"I guess that block-highmem has been around long enough, that I can
use the term 'historically' at least in the kernel sense :-)
This extra check was added for IDE because each device type driver
(ide-disk, ide-cd, etc) needed to be updated to not assume virtual
mappings of request data was valid. I only did that for ide-disk,
since this is the only one where bounce buffering really hurt
performance wise. So while ide-cd and ide-tape etc could have been
updated, I deemed it uninteresting and not worthwhile.
Now, this was just carried straight into the scsi counter parts,
conveniently, because of laziness. A quick glance at sr shows that it
too can aviod bouncing easily (no changes needed). st may need some
changes, though. So again, for scsi it was a matter of not impacting
existing code in 2.4 too much.
So TYPE_DISK check can be killed in 2.5 if someone does the work of
checking that it is safe. I'm not so sure it will make eg your SCSI
CD-ROM that much faster :-)"

[PATCH] sg.c and USER_HZ, kernel 2.5.37
Hi!
Since the introduction of USER_HZ the SG_[GS]ET_TIMEOUT ioctls may have
a serious BUG as userspace uses a different HZ from the HZ in kernelspace.
In x86 HZ=1000 and USER_HZ=100, resulting in confusing timouts as the
kernel measures time 10 times as fast as userspace.
This patch is an attempt to fix this by transforming USER_HZ based timing to
HZ based timing before storing it in timeout. To make sure that SG_GET_TIMEOUT
and SG_SET_TIMEOUT behave consistently a field timeout_user is added which
stores the exact value that's passed by SG_SET_TIMEOUT and it's returned on
SG_GET_TIMEOUT.

[PATCH] usbcore misc cleanup
This has minor usbcore cleanups:
DOC:
- the changes passing a usb_interface to driver probe() and disconnect()
weren't reflected in their adjacent docs. likewise they still said
it was possible to get a null usb_device_id (no more).
- the (root) hub API restrictions from rmk's ARM patch weren't
flagged
- mention the non-dma-coherent cache issue for usb_buffer_alloc()
- mention disconnect() cleanup issue with usb_{control,bulk}_msg()
[ you can't cancel those urbs from disconnect() ]
CODE
- make driver ioctl() use 'usb_interface' too ... this update
also resolves an old 'one instance per device' bad assumption
- module locking on driver->ioctl() was goofy, kept BKL way too
long and didn't try_inc_mod_count() like the rest of usbcore
- hcd unlink code treated iso inappropriately like interrupt;
only interrupt still wants that automagic mode
- move iso init out of ohci into shared submit_urb logic
- remove interrupt transfer length restriction; hcds that don't
handle packetization (just like bulk :) should be updated,
but device drivers won't care for now.

[PATCH] ehci-hcd, urb queuing
In doing some more extensive testing of the urb queueing behavior,
I noticed that (a) IOC wasn't always being set for each urb, while
for now it needs to be set; (b) a qh patchup wasn't done quite
where it should be. This resolves those two issues, as well
as making it a bit less noisy to unlink lots of urbs at the once.
<david-b@pacbell.net>
[PATCH] ohci-hcd, paranoia
In a test where some memory corruption happened, I noticed an
oops (null pointer exception in_irq) that's avoidable. Here's
a patch that avoids it ... anyone seeing the err() is likely
to hang some process, but that's better than the alternative.
(Also inlines some used-once routines, saving a bit of space
to make up for the new diagnostic.)

[PATCH] USB-storage: problem clearing halts
Greg, attached is a patch designed for diagnostic purposes. Please apply
to the 2.5 tree -- yes, we'll be removing this at some point in the future.
It appears that we have a problem clearing halts. This patch causes a very
clear message to be printed whenever a usb_stor_clear_halt() manages to
work. So far, I haven't seen such a thing happen. And I've seen _lots_ of
STALL conditions.
This problem has likely been around for a while... however, it hasn't been
noticed before because usb-storage was difficult to use because of other
bugs. Heck, the most recent 'bk pull' is the first one for me in _months_
which let me boot all the way into X11.
I'm going to hold my patch queue until this is resolved. On my test setup,
it's easy to see this failing. I've tried with 4 different devices, with
both UHCI and EHCI drivers. I don't want to confuse this problem with
other patches...
'result' in this function always seems to be -32. Which is odd, because
control endpoints shouldn't do that.
I'm open to suggestions as to where to look for this bug, but my instincts
are telling me that this is a core or HCD issue, not a usb-storage issue.
On a positive note, this means that the error-recovery system gets a good
workout.
<david-b@pacbell.net>
[PATCH] usb_sg_{init,wait,cancel}()
Here are the scatterlist primitives there's been mail about before.
Now the code has passed basic sanity testing, and is ready to merge
into Linus' tree to start getting wider use. Greg, please merge!
To recap, the routines are a utility layer packaging several usb
core facilities to improve system performance. It's synchronous.
The code uses functionality that drivers could use already, but
generally haven't:
- Request queueing. This is a big performance win. It lets
device drivers help the hcds avoid wasted i/o bandwidth, by
eliminating irq and scheduling latencies between requests. It
can make a huge difference at high speed, when the latencies
often exceed the time to handle each i/o request!
- The new usb_map_sg() primitives, leveraging IOMMU hardware
if it's there (better than entry-at-a-time mapping).
- URB_NO_INTERRUPT transfer flag, a hint to hcds that they
can avoid a 'success irq' for this urb. Only the urb for
the last scatterlist entry really needs an IRQ, the others
can be eliminated or delayed. (OHCI uses this today, and
any HCD can safely ignore it.)
The particular functionality in these APIs seemed to meet Matt's
requirements for usb-storage, so I'd hope the 2.5 usb-storage
code will start to use these routines in a while. (And maybe
those two scanner drivers: hpusbscsi, microtek.)
Brief summary of testing: this code seems correct for normal
reads and writes, but the fault paths (including cancelation)
haven't been tested yet. Both EHCI and OHCI seem to be mostly
OK with these more aggressive queued loads, but may need small
updates (like the two I sent yesterday). Unfortunately I have
to report that UHCI and urb queueing will sometimes lock up my
hardware (PIIX4), so while we're lots better than 2.4 this is
still a bit of a trouble spot for now.
I'll be making some testing software available shortly, which
will help track down remaining HCD level problems by giving the
queuing APIs (and some others!) a more strenuous workout than
most drivers will, in their day-to-day usage.
