    Revert "perf record: Fix crash in pipe mode"
    
    This reverts commit f766148e47d7d3b8a7128cae511971c0f793e38e which is
    commit ad46e48c65fa1f204fa29eaff1b91174d314a94b upstream.
    
    It breaks the build.  Turns out we don't test perf on stable releases,
    we need to fix that :(

    tools: sync up .h files with the repective arch and uapi .h files
    
    perf wants matching .h files otherwise it complains during the build
    process.  As these files have been modified over the past few 4.14.y
    releases, they are out of sync, so fix that problem by properly copying
    the respective versions to the tools/ mirror copies.
