[ARM] 2.5.15 PCI cleanups/fixups
2.5.15 removes the pcibios_init() call from the generic PCI layer to
the architecture layers. This allows us to clean up the ARM PCI
layer by moving the machine specific PCI initialisation from
arch/arm/kernel/bios32.c to the machine specific files.
We also fix a bug in the resource flags in the iop310 initialisation.
<rmk@flint.arm.linux.org.uk>
[ARM] 2.5.15 random fixups:
- Add SIGURG to ignored signal list.
- Ensure PFN_TO_NID is always defined on clps711x.
- Machine specific fixups take struct tag not param_struct.
- Fix pfn_valid() for non-discontigmem case.
- Make PTRACE_* available to all.
- Add PTRACE_SETOPTIONS.

<davem@nuts.ninka.net>
Tigon3: Fix typo in netgear ga320t support changes.
<kai@tp1.ruhr-uni-bochum.de>
Fix UTS_MACHINE
Remove the default for UTS_MACHINE, it gets set in
include/linux/compile.h, just as UTS_RELEASE.
(noticed by David Gibson)
<kai@tp1.ruhr-uni-bochum.de>
Fix building .i / .s files for testing
E.g. make arch/i386/kernel/process.[is] used to work at least
in the cases where the object wouldn't need any additional command
line flags defined in the local subdir.
Get back this behavior, I think I know how to do this correctly, too,
but that's for later.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Make USE_STANDARD_AS_RULE default
<ccaputo@alt.net>
net/core/sock.c: Fix typo in sysctl_{w,m}mem_default init.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Stop immediately on error
This patch restores the previous behavior of stopping the build
immediately on error (unless the -k option is given to make)
Before this patch, we would do the echo command no matter if the
compile failed, thus returning success always.
(Jan Harkes)
<kai@tp1.ruhr-uni-bochum.de>
kbuild: aic7xxx firmware build should not overwrite shipped files
o Add dependencies on generated files explicitly to the
aic7xxx Makefile - These cannot be figured out
automatically
o Rename the precompiled firmware files to
shipped_aic7xxx_{reg,seq}.h, so that we don't overwrite
shipped files when regenerating the firmware
<hch@infradead.org>
[PATCH] buffermem_pages removal (1/5)
With all work done by akpm in 2.5 Linus no more has a buffer cache
in the traditional sense. Still we try to keep estimates about
what would be the buffer cache size by keeping the number of pages
indexed by block device inodes. This is broken not only because the
old buffercache was also used for file data which is nowdays not
hashed to block device inodes and thus makes every user of this data
assume wrong numbers. Second is is possible to use block device
pages not through the buffer_head interface (i.e. userspace
block device nodes, possibly JFS also soon). In addition the atomic_t
used for this bookkepping (buffermem_pages) causes cacheline bouncing
on larger machines.
This is the first patch of a series to get rid of it. It removes the
useless output of supposedly buffer pages in show_mem(), which is used
by the magic sysrq key code.
<hch@infradead.org>
[PATCH] buffermem_pages removal (2/5)
Remove buffermem_pages showing from sgi serial code (debug only).
<hch@infradead.org>
[PATCH] buffermem_pages removal (3/5)
This one is a bit more controveral as it may break stupid userlevel
programs: remove the 'Buffers' field from /proc/meminfo and make
the Cached field show the full pagecache size instead of subtracting
the block-device backed pages.
All /proc/meminfo-using programs I have (free, top) still work fine.
<hch@infradead.org>
[PATCH] buffermem_pages removal (4/5)
This is the most discussion-worthy patch of the series: Change the
meaning of si_meminfo->bufferram from "all pages in pagecache
backed by block devices" to "all pages in pagecache".
In the header/manpage is is documented as "Memory used by buffers",
but as the buffercache is gone I think the new meaning fits the
intention from pre-pagecache days much better.
<hch@infradead.org>
[PATCH] buffermem_pages removal (5/5)
No more users of buffermem_pages are left, remove it.
While at it also remove some orphaned externs around it in swap.h
<rusty@rustcorp.com.au>
[PATCH] Futex update.
This changes futex semantics to a simple "sleep if this address
equals this value" interface, which is more convenient for building
other primitives. It also adds a timeout value.
Example library can be found at:
http://www.kernel.org/pub/linux/kernel/people/rusty/futex-2.0.tar.gz
<rusty@rustcorp.com.au>
[PATCH] Tasklet cleanup
This makes tasklet_vec and tasklet_hi_vec static inside softirq.c, and
makes them __per_cpu_data.
<hch@infradead.org>
[PATCH] fix bitop warnings in parallel port generic driver
pg tried to issue bitops on int, this fixes it to use an ulong instead.
<hch@infradead.org>
[PATCH] fix sr compile warnings
Remove an unused label and an unused variable.
<hch@infradead.org>
[PATCH] bfs header move around + warning fix
(Patch has been ACKed by the bfs maintainer)
Now that bfs no more is included in the big unions in fs.h it makes
sense to move the contents of bfs_fs_i.h and bfs_fs_sb.h to a bfs-private
location. I've created fs/bfs/bfs.h for that, also merging in bfs_defs.h.
In addition I've changed si_imap to an unsigned long pointer as the bitops
now use that type explicitly.
<mason@suse.com>
[PATCH] reiserfs 64 bit bug in get_virtual_node_size
This patch fixes a problem with reiserfs on 64 bit machines. Our
struct virtual_item is a different size there, and some calculations
that assume otherwise lead to this panic create_virtual_node:
vs-8030: create_virtual_node: virtual node space consumed
<torvalds@penguin.transmeta.com>
Move check_pgt_cache() to tlb_finish_mmu().
It should be _after_ we have flushed the TLB.
<shaggy@austin.ibm.com>
[PATCH] JFS external journal support
Additional support for external journal. We're basically adding uuid's
to both the file system and the journal to tie the two together.
<shaggy@austin.ibm.com>
[PATCH] jfs_readdir does not need to grab BKL
<petkan@mastika.lnxw.com>
[PATCH] USB pegasus driver, new vendor and device id.
new vendor and device ID
<greg@kroah.com>
[PATCH] USB Makefile bug fix
fixed problem with UHCI_HCD drivers set to 'y' were not causing the build
to go into the drivers/usb/host directory.
<Andries.Brouwer@cwi.nl>
[PATCH] usb-storage
Created the first of a series of usb-storage patches
this afternoon. Please find it below or on ftp.XX.kernel.org
under people/aeb/2.5.16-us-patch .
It removes 5% of the usb-storage code, but should, if I made
no mistake, not affect the behaviour of the code.
(This is the introduction of raw_bulk.c to hold USB-bulk
and scatter-gather code that was repeated three-five times
in various drivers. The next patch is smartmedia.c.)
<bgerst@didntduck.org>
[PATCH] cpu_has_mmx
This patch takes the cpu_has_mmx macro introduced in the xor.h header
and puts it in the proper place. It also converts the ov511 driver to
use the new macro.
<bgerst@didntduck.org>
[PATCH] cpu_has_tsc
This patch converts drivers/char/random.c and
drivers/input/joystick/analog.c to use the cpu_has_tsc macro.
<bgerst@didntduck.org>
[PATCH] remaining cpu_has cleanups
This patch cleans up the remaining direct tests against x86_capability.
It moves the cpu_has_* macros to the more appropriate
cpufeature.h. It also introduces the cpu_has() macro to test features
for individual cpus.
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Regenerate include/linux/version.h only if necessary
Before overwriting version.h, check if it actually changed - otherwise
we will unnecessarily rebuild a lot of files, as e.g. module.h depends
on version.h, and many files include module.h
<kai@tp1.ruhr-uni-bochum.de>
kbuild: Restore build nr, improve vmlinux link
People relied on the build generation number to find out if they actually
booted the right kernel, only incrementing it on config changes isn't
enough for them. So this patch goes back to the old behavior, only done
right this time:
We now don't increment the generation number on every invocation of make,
but on every link of vmlinux. At the same time, this patch fixes the
Makefile to only relink vmlinux if any of its prequisite object files
(or the command line) changed. Incrementing the version number
happens *after* we decided to relink vmlinux.

[PATCH] Update to srm_env.c driver (for Alpha arch.)
Hi Linus!
Please apply this patch. It updates the srm_env.c driver (to access
Alpha's SRM environment variables) to its current version (which is
already included in up-to-date 2.4.x kernels).
MfG, JBG
<pavel@ucw.cz>
[PATCH] suspend-to-{RAM,disk}
Here's suspend-to-{RAM,disk} combined patch for
2.5.17. Suspend-to-disk is pretty stable and was tested in
2.4-ac. Suspend-to-RAM is little more experimental, but works for me,
and is certainly better than disk-eating version currently in kernel.
Major parts are: process stopper, S3 specific code, S4 specific
code.
<pavel@ucw.cz>
[PATCH] suspend-to-{RAM,disk} fixup
Fix compile problem with suspending diabled
<pavel@ucw.cz>
[PATCH] more suspend-to-{RAM,disk} fixes
One more build fix, this time for !CONFIG_SOFTWARE_SUSPEND but
CONFIG_ACPI:
I've choosen this solution for now, as it is safest for ACPI people.
I'll modify suspend.c so that freezing part can be included without
whole suspend-to-disk support being included.
<rml@tech9.net>
[PATCH] get/put_cpu methods
This implements a get_cpu() and matching put_cpu() to safely hand out
the current CPU to avoid preempt races. Andrew and I have been bitching
about the need for such a method.
I also went ahead and replaced an example of current explicit
preempt-off with the new methods, as a case in point.
<pavel@ucw.cz>
[PATCH] One more fix for swsusp
As andrew pointed out, it is bad idea to run_task_queue() when
spinlock is held. This fixes it (only could be triggered by user
pressing Magic-D). There's minor problem left where Magic-D could be
delayed/ignored under high load. I'll either fix that or kill Magic-D
support (with acpi, it is very easy to trigger swsusp by echo 4 >
/proc/acpi/sleep, so magic key is probably not neccessary any more).
<rml@tech9.net>
[PATCH] remove preempt_disable from pdflush
It seems by the comments the statements were only there to prevent the
thread from finding itself as TASK_RUNNING after a kernel preemption.
Since we reverted to the original preemption behavior (which does not do
that) it should be safe. Looking over the code confirms - it seems to
not be doing anything evil and is properly locked otherwise.

<kai@tp1.ruhr-uni-bochum.de>
Simplify linking/building objects in subdirectories
New-style Makefiles have a nice way of declaring objects
which need to be built either built-in or as modules:
obj-$(CONFIG_EEPRO100) += eepro100.o
However, handling objects in subdirectories, which need to be
built and linked is not as nice:
subdir-$(CONFIG_E100) += e100
ifeq ($(CONFIG_E100),y)
obj-y += e100/built-in.o
endif
This means we descend into the subdirectory when building
vmlinux / modules, depending on CONFIG_XXX. When we are building
vmlinux we also need to link whatever has been built in the
subdirectory, so we add it to $(obj-y) at the appropriate place
(link order is important).
Now, the extension below allows to rewrite the second case into
obj-$(CONFIG_E100) += e100/
which looks much nicer ;-) Existing behavior is not changed, and the
only prerequisite to using the extension above is that the O_TARGET in
the subdir is named "built-in.o".

drivers/net: Simplify linking of subdirs
Use the just introduced Rules.make extension to clean up
drivers/net/*/Makefile.

[PATCH] new helpers for /proc
new helpers for seq_file - for cases where we don't have a non-trivial
iterator and just want to use seq_{printf,putc,...}.
<viro@math.psu.edu>
[PATCH] rd.c blocksize handling
Unlike other drivers, rd.c wants block size to be set once an
forever (for everybody else setting block size as high as possible and
letting filesystems change it with set_blocksize() is OK; rd.c treats
invalidate_buffers() as "kill the ramdisk contents".

[PATCH] 2.5.17 IDE 65
- Apply cleanup of host chip drivers by Bartomiej Zonierkiewicz:
affected drivers - aec62xx.c, alim15x3.c, cmd64x.c, hpt34x.c, sis5513.c
new tuning scheme (wip) part 1:
- introduce ratemask()
- use ata_timing_mode()
- use ide_config_drive_speed() return value
forward port from convert.10:
- support for AEC6280, AEC6280R
- misc cleanups
I had to fix a small typo in sis5513 code...
- Add a new entry for an old VIA cell hiding as something new.
(Pointed out by Kees Bakker.)
- Make the synchronization token active resident on the same level as the
spin lock. They interact with each other.
- Synchronize with linux-2.5.17.
- HPT366 driver typo fix by Andries Brouwer.
- Export udma_tcq_enable() symbol right now. The blk_get_request() is undefined
as well.
<dalecki@evision-ventures.com>
[PATCH] 2.5.17 IDE 66
- Move ll_10byte_cmd_build to the only place where it's used: ide-cd. The SCSI
layer does have it's own implementation which additionally it's messing
around with the hard_nr_sectors struct request value. One should *not*
provide "infrastructure" until its really used as such.
If anywhere this should reside in a file called ATAPI.
- Unfold the INIT_REQUEST macro from blk.h. This showed up plenty of duplicate
checks for QUEUE_EMPTY. Clean them as well. Remove the over cautious
major(CURRENT->rq_dev != MAJOR_NR) checks. During the last several years I
never saw any report about it. Looking at the !CURRENT->bio it is clear that
dereferencing NULL will provide the same kind of panic as the check. Some
comments around the code in question show nicely that indeed INIT_REQUEST
was a good example of code obfuscation.
- A short look at RQ_INACTIVE shows that it is only used inside the scsi.c file
and during the removal of devices. This shows that the many checks for
RQ_INACTIVE are not necessary. Looking closer even shows that some of them
did happen before checks for an empty queue. Plenty of drivers didn't care
about it and the CD-ROM ones should be handled properly, because the
most common drivers would fail as well. Comments indicate that this
was an leftover from 1.3 days...
<dalecki@evision-ventures.com>
[PATCH] 2.5.17 IDE 67
- Nuke COMMERIAL and similar spurious configuration options...
The fact that every single default configuration option contained
those bits makes this trivial patch appear rather big.
<dalecki@evision-ventures.com>
[PATCH] 2.5.16 IDE 68
- Make the different ATAPI device type drivers use a unified packet command
structure. We have to start to push them together.
This patch is rather trivial in itself, but the plentora of code duplication it
is trying to fight against is making it unfortunately rather big...
<dalecki@evision-ventures.com>
[PATCH] 2.5.17 IDE 69
- Apply small host chip driver cosmetics by Andrej xxx Panin
and Vojtech Pavlik.
- Remove support for "disc recovery time". It could only supposedly
help with really simplistic broken devices from the past,
which didn't have moderately sophisticated controllers.
And finally Vojtech voted for it as well... so I just trust him.
- Apply icside host chip driver and other ARM related updates by Russell King,
which finally settle the "portability" work a bit, well hopefully.
<viro@math.psu.edu>
[PATCH] (1/4) removal of BKL from d_move()
OK, it turned out that since the last time I've done that audit
a couple new users of d_parent had appeared. First, more crapectomy (strictly
speaking not necessary, but just look at that code - where the hell does IBM
find them?)
<viro@math.psu.edu>
[PATCH] (2/4) d_move() BKL removal
default encode_fh() doesn't take dparent_lock around messing
with dereferences of ->d_parent->d_inode->i_.... Fixed.
<david-b@pacbell.net>
[PATCH] usbcore, remove urb->next
Given the discussions of last week, this removes urb->next from
the USB core API. This change simplifies the driver API by getting
rid of a superfluous feature (and related new-developer confusion),
gets rid of a hidden failure mode (drivers can now see resubmit
failures), lets us get rid of a HCD feature that isn't consistently
implemented, and so on.
This will break some code. There are ISO drivers that don't use
urb->next (like audio), but most video drivers do. My patch #2
fixes one such driver. My patch #3 fixes host controller drivers,
most of which were already converted.
<david-b@pacbell.net>
[PATCH] cpia_usb, remove urb->next
This is the 2.5 version of the sample driver patch I sent around
last week. It updates one video driver to work with the updated
ISO API: no urb->next (explicit resubmit, with error detection)
and explicit transfer interval (HCs must remove 1 msec limit).
The 2.4 version is known to work, but usb video in 2.5 seems to
be a bit ill so this just fixes the compilation problem created
by the first of these patches.
<david-b@pacbell.net>
[PATCH] hcds, remove urb->next
This makes the hcds stop expecting urb->next to exist.
ehci-hcd ... remove obsolete sanity check
usb-uhci-hcd ... remove code (wouldn't be called)
Two "old style" drivers got updated too (uhci, usb-uhci)
so that folk can use them in case of problems with their
"new style" analogues.
<david-b@pacbell.net>
[PATCH] audio, set urb->interval
This sets urb->interval in two places it hadn't previously been set,
allowing things like SOX and XMMS to play through usb audio.
Using this and the previous patches, I was able to verify playback
of some Ogg Vorbis encoded music using most of the 2.5.17 host
controller drivers. However, "uhci-hcd" and "usb-uhci-hcd" did
not want to bind the audio driver: reading the config descriptor
(in audio.c) stalled rather consistently. That failure was seen
with the other USB 1.1 drivers too, but not as consistently.

[PATCH] 2.5.17 dquota punishment
Transform new quota code to use sysctl instead of /proc/fs.
<hch@infradead.org>
[PATCH] split namei.h out of fs.h
Currently fs.h is full of unrelated declarations and included in almost
any source file. Thus it makes sense to spilt certain aspects out that are
only used by few users.
This patch starts with the namei/path lookup interface and splits it into
<linux/namei.h> which is now directly included by the 24 files that actually
need it.

[PATCH] (3/4) BKL removal from d_move()

[PATCH] declance.c
"Maciej W. Rozycki" <macro@ds2.pg.gda.pl>: [patch] 2.4.19-pre7: A few declance multicast updates:
Hello,
It seems all Ethernet device drivers were bulk-converted to use the new
common CRC functions. I discovered declance used incorrect endianness to
calculate the sum for its multicast filter and had a few alignment
problems there. I fixed these bugs in the MIPS/Linux CVS tree which is at
2.4.18 now. Here is the respective update for the official kernel.
The bugs make the filter non-functional. Please apply.

[PATCH] sigio delivery fix
Stephen Rothwell <sfr@canb.auug.org.au>: fix for sigio delivery:
Hi Linus,
This patch means that we keep the upper 16 bits of the si_code
field of the siginfo structure that is delivered with and SIGIOs.
We need this so that the code that actually copies the siginfo_t
out to user mode knows which part of the union to copy. We currently
get away with out this information because we always copy at least
two ints worth of the union, but this s an ugly hack and I would
like to tidy it up.
Comments?

[PATCH] smp_call_function doco fix
Trivial patch update against 2.5.17:
dipankar@in.ibm.com: smp_call_function change:
My earlier patch fixed only i386. As per Dave Miller's suggestion,
I have fixed smp_call_function for other smp architectures too.
Description
-----------
Going by the documentation and use of _bh version of spin_lock(),
smp_call_function() is allowed to be called from BH context,
We can run into a deadlock with some locks if we do so.
This because reader-writer locks can sometimes be used optimally
by not disabling irqs while taking the reader side if only the
reader side of the lock is taken from irq context.
CPU #0 CPU #1
read_lock(&tasklist_lock)
write_lock_irq(&tasklist_lock)
[spins with interrupt disabled]
[Interrupted by BH]
smp_call_function() for BH
handler
[ doesn't take the IPI]
So, cpu #1 doesn't take the IPI and cpu #0 spinwaits
for the IPI handler to start, resulting in a deadlock.
The last time I looked, I couldn't see smp_call_function() being
called from BH context anywhere. So, there is no immediate problem.
However it seems right to correct the documentation and also not
disable BH while taking the call lock since it isn't necessary.
This patch does exactly that.
Thanks

[PATCH] jiffies.h
Trivial patch update against 2.5.17:
Tim Schmielau <tim@physik3.uni-rostock.de>: move jiffies from sched.h to it's own jiffies.h:
Move 'jiffies' from sched.h to their own header.
Then pull the sched.h dependency from 67 files that include sched.h for
no apparent reason other than the jiffies declaration.
Move the time_[before,after}{_eq}() macros from timer.h to jiffies.h,
since there are *no* files using them that don't also use jiffies.
Many more sched.h dependencies can be killed after capable(),
request_irq(), and free_irq() are moved out of <linux/sched.h>.

[PATCH] possible fix for broken floppy driver, take 2
Here is an updated patch for the floppy driver which got broken in
2.5.13. "read block 0 on ->revalidate()" is now implemented through
the bio interface, following a suggestion by Christoph Hellwig.
I still cannot explain why block_dev.c's ->bd_block_size change
caused data corruption, but removing that code fixes the floppy
driver and doesn't seem to cause any problems on my test box.

[PATCH] include buffer_head.h in actual users instead of fs.h (1/10)
Now that fs.h grow due to the lock.h removal let's reduce it's overhead
again: Instead of penalizing ever user of fs.h with the overhead of the
buffer head interface let it's users include it directly.
This also shows nicely which parts of the core kernel still depend on the
buffer head interface, and allows that to be cleaned up properly.
This is the first of ten patches and adds the includes needed by
buffer_head.h to it and fixes it's inclusion guard.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (2/10)
Declare buffer_init() extern in init/main.c like the other _init so that
it doesn't have to include buffer_head.h. Remove buffer_init() there.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (3/10)
Remove unused bh_kmap/bh_kunmap inlines from highmem.h.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (4/10)
Remove two unused declarations in fs/jffs/intrep.h.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (5/10)
Include buffer_head.h directly in the file in drivers/ that need it
(9 files). Note that most of this uses are layering violations that I
will address later.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (6/10)
Make the 7 file that need it in mm/ include buffer_head.h directly.
Once again most files shouln't need it and want fixing.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (7/10)
Make the 5 headers in include/linux that need it include buffer_head.h
directly.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (8/10)
Make kernel/ksyms.c include buffer_head.h directly.
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (9/10)
Make the 144 files in fs/ that need it include buffer_head.h directly.
Again some uses in the VFS files are layering violations and need to
be addressed later. The new include statement gives a nice grep pattern
for that :)
<hch@infradead.org>
[PATCH] include buffer_head.h in actual users instead of fs.h (10/10)
No more need to include buffer_head.h in fs.h. Finally.

[PATCH] 2.5.17 IDE 70
- Apply host chip driver cleanups by Bartomiej Zonierkiewicz.
- Take the draft device type driver implementation from Adam Richter and make
it actually work with some of the drivers we have at hand. Quite a lot
of it was fixed by me as well to have the desired effects.
We have added a attach method for the sub device type drivers to make it
possible dor sub device type drivers to attach devices to the overall
infrastructure. UNIX has something like this SCSI code is implementing
something like this, just for some unknown reasons Linux block device
operations don't have it...
- ide_drive_t is finally gone. Please use struct ata_device instead.
Hint the ide.h specific byte type should go over time as well, sine there
is no need to invent something already handled by the kernel. Please use
the unambigious u8 type instead where possible.
- Add a bit of documentation about cabling issues. ide.txt needs a lot of
improvement at some time still.

[PATCH] swsusp fixes
This kills unneccessary include from ide-disk.c, kills #ifdef from
