      [PATCH] m68k interrupt handling fix · 5d5c8930
      Andrew Morton authored
      From: Geert Uytterhoeven <geert@linux-m68k.org>
      
      The syscalls.h change broke the m68k interrupt management code, since
      sys_{request,free}_irq() are not syscalls, but routines to manage system
      (CPU) interrupts.

      [PATCH] swsusp: fix error handling in "not enough swap space" · f57a9b9f
      Andrew Morton authored
      From: Pavel Machek <pavel@ucw.cz>
      
      Without this, if there's not enough swapspace, suspend fails, but leaves
      devices suspended, leading to dead machine.

      [PATCH] firmware loader: pin firmware module · 8813723a
      Andrew Morton authored
      From: Dmitry Torokhov <dtor_core@ameritech.net>
      
      We need to pin the firmware loader module until the last reference to the
      firmware class device is dropped and the class device is destroyed.

      [PATCH] convert pdflush to kthread · a4f10cfd
      Andrew Morton authored
      From: Keith Owens <kaos@sgi.com>
      
      New pdflush threads are launched on-demand by pdflush.
      
      It turns out that on some architectures (eg, ia64) a kernel thread inherits
      its parent's stack utilisation.  So after the thread-launches-a-thread
      cycle has progressed sufficiently far we run out of stack space and crash.
      
      Simple fix: convert pdflush to use kthreads.  All kthreads are parented by
      keventd so there is no stack windup as a result of pdflush launching
      pdflush.

      [PATCH] x86-64 fixes for 2.6.4rc1 · 2955399d
      Andrew Morton authored
      From: Andi Kleen <ak@suse.de>
      
      Fix a few issues on x86-64 for 2.6.4rc1.
      
      The 32bit emulation used 4GB/3 for the mmap break. This actually gave
      programs less sbrk space than with a standard 32bit kernel. Move the 32bit
      mmap break to 0xc5000000.
      
      Uses the correct gcc option to optimize for Prescott now (requires a very
      new mainline gcc)
      
      Also merge the i386 sched_clock().  I hope this will fix some interactivity
      problems with the scheduler.
      
      - Change initializer to new style (Arnd Bergmann)
      - Remove 2 sibling limit in HT support (from i386)
      - Always log RIP in MCE records even when not exact
      - Move 32bit program task break up to 0xc5000000 by default
      - Use -march=prescott for Prescott optimized kernel if possible
      - Don't divide by zero with report_lost_ticks on and HPET off
      - Merge preempt/smp/debug_pagealloc oops printing from i386
      - Add pfn_to_nid()
      - Merge more accurate sched_clock from i386
      - Remove traces of debugging code in mce.c
      - Update defconfig

      [PATCH] Make powernow-k8 cpufreq control work again · a1f34321
      Andrew Morton authored
      From: Pavel Machek <pavel@suse.cz>
      
      We curretly have an off-by-factor-of-1000:
      
      cat /proc/cpufreq
      
                minimum CPU frequency  -  maximum CPU frequency  -  policy
      CPU  0         2000 kHz (100 %)  -       2000 kHz (100 %)  -  powersave
      
      
      I do not have explanation why it is 2MHz - 2MHz.  On my system I removed
      bug which prevented my system from being reported as 0.8MHz - 1.8MHz.  (And
      modulo cosmetic uglyness, it worked).
      
      This fixes cosmetic uglyness, adds proper copyrights, removes warning
      "untested on PREEMPT" (someone tested it, and makes it easier to override
      PST by user (eMachine users will need that one).

      [PATCH] Fix network hashtable sizing · a78fd404
      Andrew Morton authored
      The new networking hashtable sizing is all bollixed up.  The logic is wrong
      and tcp is setting it to the logarithm of what was intended.  Heaven knows.
      
      Fix it up so that the sizing is the same as it used to be in 2.6, with a
      boot-time override.  Which was what was intended.

      [PATCH] sys_alarm() return value fix · fb6c1a0c
      Andrew Morton authored
      From: Kurt Garloff <garloff@suse.de>
      
      when calling
      
      alarm(1); alarm(0);
      
      the second alarm can wrongly return 2. This makes an LSB test fail.
      
      It happens due to rounding errors in the timeval to jiffie conversion and
      back.  On i386 with HZ =3D=3D 1000, there would not need to be rounding
      error IMVHO, but they even occur there.  On HZ=3D1024 platforms, they may
      even be unavoidable.
      
      Attached patch fixes the return value of alarm().

      [PATCH] Fix VT mode change vs. fbcon · c0ce26a8
      Andrew Morton authored
      From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
      
      This patch implements what we discussed earlier to fix the switch bewteen
      KD_GRAPHICS and KD_TEXT.
      
      It has been tested for a few days now and appear to resolve the problem for
      affected users.
      
      James: I know you have some objections, I don't fully agree with them, and
      I want that in asap now, that bug has been plaguing fbdev since the very
      beginning and it's time to get rid of that and my corresponding todolist
      entry.  You are welcome to propose a patch on top of this one if you feel
      you can make things cleaner.  The approach of adding a parameter to
      con_blank() is Linus idea btw :)
      
      I didn't add a separate function as that would have made the butchering of
      drivers/char/vt beyond what I want to deal with in 2.6.

      From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>
      
      The following patches fixes tty drivers which dont set devfs_name. Not
      doing so will cause the tty layer to create "/dev/<NULL>x" entries when
      devfs is being used.
      
      I used "drivername/" in isicom and pcxe because the letter used to
      identify them are already used by other drivers.

      [PATCH] revert the /proc thread visibility fix · 5d8087c3
      Andrew Morton authored
      It appears that gdb, perfmon and perhaps other applications are already
      opening /proc/<tid> even though it does not appear in /proc readdir output
      and is available under its group leader's directory anyway.
      
      Apparently ascertaining the group leader is hard for gdb and thsi trick
      always worked for LinuxThreads apps.
      
      So revert this change.

      [PATCH] fix umount dataloss problem · eb657e38
      Andrew Morton authored
      address_spaces have a `dirtied_when' jiffies field which records the time at
      which the mapping was first dirtied.  This is used for the periodic writeback
      (kupdate) function.  It is also used to prevent livelocks in the writeback
      code: don't try to write back objects which were dirtied after
      sync_sb_inodes() was called.
      
      It used to be the case that dirtied_when == 0 had magical properties, so
      there is code in there which avoids accidentally setting dirtied_when to zero
      at jiffy wrap time.  We just set it to jiffies|1.
      
      Unfortunately, jiffies|1 is in the future.  So under some rare timing
      circumstances (inode dirtied within one jiffy of umount) the livelock
      avoidance code in sync_sb_inodes() can accidentally trigger and we fail to
      write an inode out, resulting in filesytem corruption on ext2-style
      filesystems.  Normally, nobody dirties a file within a millisecond of umount,
      so it was not noticed.
      
      It is no longer the case that (address_space.dirtied_when == 0) has special
