      [PATCH] Add error checking get_disk() · d99c48c6
      Andrew Morton authored
      Patch from Bob Miller <rem@osdl.org>
      
      The get_disk() function should check the return value from kobject_get()
      before passing it to to_disk().  This patch fixes this error.

      [PATCH] Fix nfsd_symlink() failure path · 18f3cae2
      Andrew Morton authored
      Patch from Andreas Gruenbacher <agruen@suse.de>
      
      In both 2.5 and 2.4, the fs/nfsd/vfs.c:nfsd_symlink() function calls down to
      notify_change().  If notify_change fails for some reason, the error code is
      not converted to an nfs no-the-wire error code as is should.  The attached
      patches fix that (one for 2.4, the other for 2.5).

      [PATCH] Tighten CONFIG_NUMA preconditions · 34b254ca
      Andrew Morton authored
      Patch from Martin J. Bligh and Dave Hansen
      
      People with ordinary PCs are accidentally turning on NUMA support, and people
      with NUMA machines are finding the NUMA option mysteriously disappearing.
      This patch sets the defaults to sane things for everyone, and only allows you
      to turn on NUMA with both SMP and 64Gb support on (it's useful for the
      distros on non-Summit boxes, but not on their UP kernels ;-)).
      
      I've also moved it below the highmem options, as it logically depends on
      them, so this makes more sense.  For those searching for NUMA support on
      *real* NUMA machine, Dave has provided some guiding comments to show them
      what they messed up (it's totally non-obvious).  Hopefully this will stop
      people's recent unfortunate foot-wounds (I think UP machines were defaulting
      to NUMA on ...  oops).

      [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.

      better be setup by then

      [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: less locking · 8e82373a
      Andrew Morton authored
      - optimise file_kill() to not take the global lock if the file is not on a
        list.
      
      - Use optimised file_kill() in a few places rather than open-coding the
        list removal.

      [PATCH] file_table: remove the private freelist · 4cac8a28
      Andrew Morton authored
      - Remove the private freelist.  There's no point in special-casing file
        structure allocations in this way.
      
      - Hence the freeing of files can be moved outside file_list_lock()
      
      - Replace euid test with capable(CAP_SYS_ADMIN).
      
      - Tidy various other things up.

      [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.

      - uninline internal_add_timer().  Saves half a kilobyte of text.

      [PATCH] Pass the load address into ELF_PLAT_INIT() · 544db1a2
      Andrew Morton authored
      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.
