      Remove *.rej pattern from .gitignore · 1f5d3a6b
      S.Çağlar Onur authored
      With commit 3f1b0e1f ".gitignore update"
      Linus's current git tree starts to ignore any "*.rej" files.
      So "git status" no longer shows these files, but the ones who works with
      quilt patchsets, this not makes life easier as expected.
      Because sometimes a work flow (at least for me) requires
      "quilt push -f" followed by "git status" to see unresolved merge
      conflicts, work on these conflicts to correct them and finalize
      the patch with "quilt refresh".
      And if there are some "*.rej" files exists in tree, for whatever
      reason, this means something goes really wrong there and i think
      this situation not deserves to be ignored.

      kbuild: disable modpost warnings for linkonce sections · fd1db0a3

      Disable modpost warnings for linkonce sections
      My build gives lots of warnings like
      WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): unexpected section name.
      The (.[number]+) following section name are ld generated and not expected.
      Did you forget to use "ax"/"aw" in a .S file?
      Note that for example <linux/init.h> contains
      section definitions for use in .S files.
      But for .linkonce. duplicated sections are actually ok and expected.
      So just disable the warning for this case.

      kbuild: escape meta characters in regular expression in make TAGS · a95bcfac
      Masatake YAMATO authored
      Alexey Dobriyan <adobriyan@gmail.com> introduced a code adds
      menuconfig SOMETHING in Kconfig to tags output when you did "make tags".
      See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=80ff26241623875636674a31c0540a78c0fb5433
      "make tags" may work fine with his code. However make TAGS doesn't work well
      because etags command requires backslashes to escape meta characters like
      `(', `)' and `|'.
      Here is a patch.

      BKL: revert back to the old spinlock implementation · 8e3e076c
      Linus Torvalds authored
      The generic semaphore rewrite had a huge performance regression on AIM7
      (and potentially other BKL-heavy benchmarks) because the generic
      semaphores had been rewritten to be simple to understand and fair.  The
      latter, in particular, turns a semaphore-based BKL implementation into a
      mess of scheduling.
      The attempt to fix the performance regression failed miserably (see the
      previous commit 00b41ec2 'Revert
      "semaphore: fix"'), and so for now the simple and sane approach is to
      instead just go back to the old spinlock-based BKL implementation that
      never had any issues like this.
      This patch also has the advantage of being reported to fix the
      regression completely according to Yanmin Zhang, unlike the semaphore
      hack which still left a couple percentage point regression.
      As a spinlock, the BKL obviously has the potential to be a latency
      issue, but it's not really any different from any other spinlock in that
      respect.  We do want to get rid of the BKL asap, but that has been the
      plan for several years.
      These days, the biggest users are in the tty layer (open/release in
      particular) and Alan holds out some hope:
        "tty release is probably a few months away from getting cured - I'm
         afraid it will almost certainly be the very last user of the BKL in
         tty to get fixed as it depends on everything else being sanely locked."
      so while we're not there yet, we do have a plan of action.

      Revert "semaphore: fix" · 00b41ec2
      Linus Torvalds authored
      This reverts commit bf726eab, as it has
      been reported to cause a regression with processes stuck in __down(),
      apparently because some missing wakeup.
      Quoth Sven Wegener:
       "I'm currently investigating a regression that has showed up with my
        last git pull yesterday.  Bisecting the commits showed bf726e
        "semaphore: fix" to be the culprit, reverting it fixed the issue.
        Symptoms: During heavy filesystem usage (e.g.  a kernel compile) I get
        several compiler processes in uninterruptible sleep, blocking all i/o
        on the filesystem.  System is an Intel Core 2 Quad running a 64bit
        kernel and userspace.  Filesystem is xfs on top of lvm.  See below for
        the output of sysrq-w."
      for full report.
      In the meantime, we can just fix the BKL performance regression by
      reverting back to the good old BKL spinlock implementation instead,
      since any sleeping lock will generally perform badly, especially if it
      tries to be fair.

      Move ACCESS_ONCE() to <linux/compiler.h> · 9c3cdc1f
      Linus Torvalds authored
      It actually makes much more sense there, and we do tend to need it for
      non-RCU usage too.  Moving it to <linux/compiler.h> will allow some
      other cases that have open-coded the same logic to use the same helper
      function that RCU has used.
