      [PATCH] fix ips driver compile problems · a5297c70
      Dave Hansen authored
         This patch has been floating inside IBM for a bit, but it appears
      that no one passed it back up to you, yet.  I don't know who wrote it,
      but it applies to 2.5.8 and the ServeRAID driver works just fine with it
      applied.  Without it, the driver fails to compile.

      [PATCH] prctl() patch · feef9b8a
      David Mosberger authored
      This is the patch to add support for PR_SET_FPEMU/PR_GET_FPEMU to give
      per-process control over fp-emulation handling.  It also cleans up the
      way PR_SET_UNALIGN_CTL/PR_GET_UNALIGN_CTL are implemented.

      [PATCH] swapinfo accounting · c6df0ff4
      Hugh Dickins authored
      Randy observed that 2.5 /proc/meminfo SwapFree holds steady
      while SwapTotal goes up and down: wrong way round!
      
      Andrew pointed to wrong conditional in si_swapinfo(): 2.5.4
      updated it incorrectly when new flags bit was briefly added.
      And pointed out that it also makes si_swapinfo much too slow.

      Martin Dalecki authored
      - Consolidate ide_choose_drive() and choose_drive() in to one function.
      
      - Remove sector data byteswpapping support. Byte-swapping the data is supported
         on the file-system level where applicable.  Byte-swapped interfaces are
         supported on a lower level anyway. And finally it was used inconsistently.
      
      - Eliminate taskfile_input_data() and taskfile_output_data(). This allowed us
         to split up ideproc and eliminate the ugly action switch as well as the
         corresponding defines.
      
      - Remove tons of unnecessary typedefs from ide.h
      
      - Prepate the PIO read write code for soon overhaul.
      
      - Misc small bits here and there :-).

      Handle $(export-objs) ambiguity · e13a5e16
      Kai Germaschewski authored
      We use the makefile variable $(foo-objs) to list the objects
      a composed module foo.o is supposed to be composed of.
      
      We use the special varible $(export-objs) to list the object files which
      export symbols.
      
      This oviously clashes in the case of foo == export. There's basically
      two ways to handle it: (1) rename one of these options, like 
      foo-objs to foo-parts or something, or (2) simply disallow a composite
      object called export.o, so you never need $(export-objs) to list its
      parts.
      
      As (1) would affect basically all Makefiles in the tree and (2) doesn't
      seem much of a limitation, I went for (2).

      [PATCH] PATCH - Create "export_operations" interface for filesystems to describe · dcd21270
      Neil Brown authored
      Create "export_operations" interface for filesystems to describe
      whether and how they should be exported.
      
      - add new field in struct super_block "s_export_op" to describe
        how a filesystem is exported (i.e. how filehandles are mapped to
        dentries).
      - New module: fs/exportfs for holding helper code for mapping between
        filehandles and dentries
      - Change nfsd to use new interface if it exists.
      - Change ext2 to provide new interface
      - Add documention to filesystems/Exporting
      
      If s_export_op isn't set, old mechanism still works, but it is
      planned to remove old method and only use s_export_op.

      Prepare for new export_operations interface (for filehandle lookup):

       - modify d_move to work with anonymous dentries (IS_ROOT dentries)
       - modify d_find_alias to avoid anonymous dentries where possible
         as d_splice_alias and d_alloc_anon use this
       - put in place infrastructure for s_anon allocation and cleaning
       - replace a piece of code that is in nfsfh, reiserfs and fat
         with a call to d_alloc_anon
       - Rename DCACHE_NFSD_DISCONNECTED to DCACHE_DISCONNECTED

      [PATCH] migration_thread preempt fix · e1efc1f3
      Robert Love authored
      This fixes a race in migration_thread which results in a deadlock on
      boot for some SMP systems.  The fix is to to disable preemption inside
      of set_cpus_allowed.
      
      Andrew Morton first noticed the problem and provided the following patch
      a few weeks back.  I was not affected until the recent migration_init
      fix, for some odd reason.  Neither Andrew nor I think this is actually
      kernel preemption's fault but perhaps a race in the tricky behavior of
      the migration code.

      [PATCH] don't allocate ratnodes under PF_MEMALLOC · 49c7ca7c
      Andrew Morton authored
      On the swap_out() path, the radix-tree pagecache is allocating its
      nodes with PF_MEMALLOC set, which allows it to completely exhaust the
      free page lists(*).  This is fairly easy to trigger with swap-intensive
      loads.
      
      It would be better to make those node allocations fail at an earlier
      time.  When this happens, the radix-tree can still obtain nodes from its
      mempool, and we leave some memory available for the I/O layer.
      (Assuming that the I/O is being performed under PF_MEMALLOC, which it
      is).
      
      So the patch simply drops PF_MEMALLOC while adding nodes to the
      swapcache's tree.
      
      We're still performing atomic allocations, so the rat is still biting
      pretty deeply into the page reserves - under heavy load the amount of
      free memory is less than half of what it was pre-rat.
      
      It is unfortunate that the page allocator overloads !__GFP_WAIT to also
      mean "try harder".  It would be better to separate these concepts, and
      to allow the radix-tree code (at least) to perform atomic allocations,
      but to not go below pages_min.  It seems that __GFP_TRY_HARDER will be
      pretty straightforward to implement.  Later.
      
      The patch also impements a workaround for the mempool list_head
      problem, until that is sorted out.
      
      
      
      (*) The usual result is that the SCSI layer dies at scsi_merge.c:82.
      It would be nice to have a fix for that - it's going BUG if 1-order
      allocations fail at interrupt time.  That happens pretty easily.
