      [PATCH] /proc/sysrq-trigger: trigger sysrq functions via · 5d954f33
      Andrew Morton authored
      This makes sysrq facilities available to remote users.
      
      Writing a 'C' to /proc/sysrq-trigger receives the same treatment as typing
      sysrq-C on the local keyboard.

      [PATCH] io-apic.c: DO_ACTION cleanup · 648300b0
      Andrew Morton authored
      Patch from "Martin J. Bligh" <mbligh@aracnet.com>
      
      This removes the DO_ACTION stuff.  The downside is that we add some boring
      and repetive code.  The upside is that it's simple, and mere mortals can read
      it without screwing their brains into a small piece of silly putty and
      bouncing it off the wall.  I think that's more important than pure source
      code size.

      [PATCH] OOPS instance counters · 93b24206
      Andrew Morton authored
      Patch from "Randy.Dunlap" <rddunlap@osdl.org>
      
      Adds an oops counter to the oops messages, such as:
      
      	Oops: 0002 [#2]
      
      So we can tell whether oops reports refer to the first oops, or to some
      less-interesting followon oops.

      [PATCH] slab changes for !CONFIG_MMU · 56646aa2
      Andrew Morton authored
      Patch from Christoph Hellwig <hch@lst.de>
      
      It extends the maximum amount of memory which may be kmalloced on nommu
      machines.  This is needed because these machines cannot perform vmalloc().
      
      We couldn't really find a way of doing this which avoided the ifdef tangle.

      [PATCH] file_list_lock contention fixes · cc6c76b9
      Andrew Morton authored
      Patch from Manfred Spraul <manfred@colorfullife.com>
      
      Fixes the lock contention over file_list_lock by simply removing the unneeded
      anon_list.  So filp allocation does not need to take a global lock any more.
      
      The use of a spinlock to protect files_stat.nr_files is a bit awkward, but
      the alternative is a custom sysctl handler, and isn't much more efficient
      anyway.

      [PATCH] timer re-addition lockup fix · bb8c9453
      Andrew Morton authored
      This is a forward-port of Andrea's fix in 2.4.
      
      If a timer handler re-adds a timer to go off right now, __run_timers() will
      never terminate.  (I wrote a test.  It happens.)
      
      Fix that up by teaching internal_add_timer() to detect when it is being
      called from within the context of __run_timers() and to park newly-added
      timers onto a temp list instead.  These timers are then added for real by
      __run_timers(), after it has finished processing all pending timers.

      Patch from Anton Blanchard <anton@samba.org>
      
      With ppc64 64bit dynamic executables we have to relocate the contents of the
      function descriptor.  Passing in the load address to ELF_PLAT_INIT allows us
      to do this.
      
      The patch allows ppc64 to run 64-bit executables and is a no-op for other
      architectures.

      [PATCH] Fix noirqbalance · eb5ef7e6
      Andrew Morton authored
      Patch from Zwane Mwaikambo <zwane@linuxpower.ca>
      
      This patch fixes what seems to have been a longstanding bug. Ever since we
      moved cpu bringup later into the boot process, we end up programming the
      ioapics before we have any of our possible cpus in the cpu_online_map.
      Therefore leading to the following current situation;
      
      For walmart-smp, bigsmp and summit we set the logical destination for cpu
      to TARGET_CPUS which can depend on the cpu_online_map, so what you would
      normally see with noirqbalance would be all interrupts handled on cpu0
      since at that stage no other cpu apart from the BSP is online.
      
      You can check for this by looking at the ioredtbls at boottime for a two
      way system;
      
      .... IRQ redirection table:
       NR Log Phy Mask Trig IRR Pol Stat Dest Deli Vect:
       00 000 00  1    0    0   0   0    0    0    00
       01 001 01  0    0    0   0   0    1    1    39
       02 001 01  0    0    0   0   0    1    1    31
       03 001 01  0    0    0   0   0    1    1    41
       04 001 01  0    0    0   0   0    1    1    49
       05 001 01  0    0    0   0   0    1    1    51
       06 001 01  0    0    0   0   0    1    1    59
      
      Notice that 'Log' is set to 1 instead of 3.
      
      This patch will simply reprogram all the ioredtbls to handle the other
      online cpus.
      
      Patch tested on my 2way P2-400 and a 16way NUMAQ both with noirqbalance.
      It will not affect the irqbalance case because we are simply setting
      TARGET_CPUS which is done anyway.

      [PATCH] signal fix for wedge on multithreaded core dump · 874f2e47
      Roland McGrath authored
      This is a fix made almost a month ago, during the flurry of signal changes.
      I didn't realize until today that this hadn't made it into 2.5.  Sorry
      about the delay.
      
      This fix is necessary to avoid sometimes wedging in uninterruptible sleep
      when doing a multithreaded core dump triggered by a process signal (kill)
      rather than a trap.  You can reproduce the problem by running your favorite
      multithreaded program (NPTL) and then using "kill -SEGV" on it.  It will
      often wedge.  The actual fix could be just a two line diff:
      
      +                       if (current->signal->group_exit)
      +                               goto dequeue;
      
      after the group_exit_task check.  That is the fix that has been used in
      Ingo's backport for weeks and tested heavily (well, as heavily as core
      dumping ever gets tested, but it's been in our production systems).
      
      But I broke the hair out into a separate function.  The patch below has the
      same effect as the two-liner, and no other difference.  I have tested
      2.5.64 with this patch and it works for me, though I haven't beat on it.
      
      The way the wedge happens is that for a core-dump signal group_send_sig_info
      does a group stop of other threads before the one thread handles the fatal
      signal.  If the fatal thread gets into do_coredump and coredump_wait first,
      then other threads see the group stop and suspend with SIGKILL pending.
      All other fatal cases clear group_stop_count, so this is the only way this
      ever happens.  Checking group_exit fixes it.  I didn't make do_coredump
      clear group_stop_count because doing it with the appropriate ordering and
      locking doesn't fit the organization that code.

      [PATCH] fix affs/super.c · e54f721e
      Andries E. Brouwer authored
      Mounting a non-affs filesystem as affs crashes the kernel.

      	memset(sbi, 0, sizeof(*AFFS_SB));
      where the second sizeof is 1, so that sbi is not zeroed at all.
      
      Also, avoid a warning for printk of sector_t in amigaffs.h.

      There is a logic error in ext2_new_block().  If we manage to reserve some

      I recently noticed a bug in ext2/3; newly created inodes which inherit
      the noatime flag from their containing directory do not respect noatime
      until the inode is flushed from the inode cache and then re-read later.
      This is because the code which checks the ext2 no-atime attribute and
      then sets the S_NOATIME in inode->i_flags is present in
      ext2_read_inode(), but not in ext2_new_inode().
      
      I fixed this in 2.4, and then found an even worse bug in the 2.5 code;
      the DIRSYNC flag is completely ignored *except* in the case where a
      directory is newly created using mkdir and its parent directory has the
      DIRSYNC flag.  S_DIRSYNC doesn't get set in the ext2_new_inode() or the
      ext2_ioctl() paths (which is used by chattr).
      
      This patch centralizes the code which translates the ext2 flags in the
      raw ext2 inode to the appropriate flag values in inode->i_flags in a
      single location.  This fixes the bug, makes things cleaner, and also
      removes 30 lines of code and 128 bytes of compiled x86 text in the
      bargain.
