      [PATCH] Fix for hotplug of multifunction cards. · 0e1311b1
      Andrew Morton authored
      From: Linda Xie <lxiep@us.ibm.com>
      
      The changes in this patch are for multifunction cards insertions/removals
      and  bug fixes:
      
      1. fix up new nodes' linux_phandle field.
      2. new nodes' phb, devfn(and so on) need to be fixed even the nodes don't
      	have "interrupts".
      3. change of_remove_node to non-recurisve func. The recursions will be done
      	by the caller.
      4. add a new function -- of_finish_dynamic_node_interrupts()

      [PATCH] iostats averaging fix · 14c781b8
      Andrew Morton authored
      From: Rick Lindsley <ricklind@us.ibm.com>
      
      Fix bug #2230.
      
      I've corresponded with the submitter and he did find a real bug -- when we
      were merging I/O requests we didn't always take the oldest request start
      time, which would cause a couple of the calculations like wait time and
      average queue size to be too small.  He found it mathematically but having
      done so, I think logic and inspection makes it easy to verify.

      we can end up calling blk_congestion_wait() before the waitqueue_heads are set
      up.

      [PATCH] kill INIT_THREAD_SIZE · aae898de
      Andrew Morton authored
      From: Matt Mackall <mpm@selenic.com>
      
      This piece of the THREAD_SIZE cleanup got dropped.  If you make THREAD_SIZE
      > 8k, the init thread overlaps the .init section and gets smashed.  I've
      gone ahead and killed INIT_THREAD_SIZE throughout as it wasn't doing much.
      This also saves 4k when we use 4k stacks.  Please apply.  Couple more minor
      pieces remaining.

      [PATCH] slab: fix display of object length in corruption detector · dac10907
      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      print_objinfo() dumps the first few characters of an interesting object for
      debugging.  It used the wrong object len (including debug padding, instead
      of just the data area), which could cause an oops if DEBUG_PAGEALLOC is
      enabled.

      [PATCH] do_write_mem() return value check · 055a54db
      Andrew Morton authored
      From: BlaisorBlade <blaisorblade_spam@yahoo.it>, and me
      
      - remove unused `file *' arg from do_write_mem()
      
      - Add checking for copy_from_user() failures in do_write_mem()
      
      - Return correct value from kmem writes() when a fault is encountered.  A
        write()-style syscall's return values are:
      
         0 when nothing was written and there was no error (someone tried to
         write zero bytes)
      
         >0: the number of bytes copied, whether or not there was an error.
         Userspace detects errors by noting that the write() return value is less
         than was requested.
      
         <0: there was an error and no bytes were copied

      [PATCH] reiserfs: fix transaction sizes · 134ab3f5
      Andrew Morton authored
      From: Chris Mason <mason@suse.com>
      
      Make sure reiserfs uses a reasonable number when restarting long unbounded
      transactions (creating holes or deleting files).
      
      Without this patch, the number of blocks requested grows with each
      transaction restart, until it hits MAX_BATCH_COUNT and starts forcing
      commits with every new transaction.

      From: Jeff Mahoney <jeffm@suse.de>
      
      fsstress manages to setup a sequence of events that allow an attempt to
      perform direct-io on a tail.  bh_result->b_page == NULL, which causes the
      PageLocked and PageWriteback checks to perform a NULL deref, causing the
      oops.

      Andrew Morton authored
      From: James Simmons <jsimmons@infradead.org>
      
      This patch merges two of the drawing functions.  The patch uses aligned
      transfers when possible even on displays where the characters are not byte
      align.  Tested on my my laptop for 12 bit width fonts and 8 bit wide fonts.
      It works very nicely.

      [PATCH] page_referenced() simplification · 54c50cc5
      Andrew Morton authored
      There's no point in calling mark_page_accessed() here.  The page is never on
      the LRU so all mark_page_accessed() will do is to set PG_referenced, which we
      immediately clear again.

      [PATCH] flush_scheduled_work() deadlock fix · b9b52730
      Andrew Morton authored
      Because keventd is a resource which is shared between unrelated parts of the
      kernel it is possible for one person's workqueue handler to accidentally call
      another person's flush_scheduled_work().  thockin managed it by calling
      mntput() from a workqueue handler.  It deadlocks.
      
      It's simple enough to fix: teach flush_scheduled_work() to go direct when it
      discovers that the calling thread is the one which should be running the
      work.
      
      Note that this can cause recursion.  The depth of that recursion is equal to
      the number of currently-queued works which themselves want to call
      flush_scheduled_work().  If this ever exceeds three I'll eat my hat.

      [PATCH] selinux: fix compute_av bug · e6c51795
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch fixes a bug in the SELinux compute_av code; the current code
      yields the right access computation but can cause unnecessary (but
      harmless) processing to occur when transition permission wasn't granted in
      the first place by the TE configuration.  Thanks to Chad Hanson of TCS for
      reporting the bug.

      [PATCH] kbuild: fix modpost when used with O= · 4a116813
      Andrew Morton authored
      From: Sam Ravnborg <sam@ravnborg.org>
      
      modpost or to be more specific sumversion.c was not behaving correct when
      used with O= and MODULE_VERSION was used.  Previously it failed to use
      local .h when calculation the md-sum in case of a O= build.
      
      The following patch introduces the following:
      
      - A generic get_next_line()
      
      - Check that the topmost part of the directory matches
      
      - Using strrch when checking for file with suffix .o
      
      - Use NOFAIL for allocations in sumversion
      
      - Avoid memory leak in new_module
      
      The generic get_next_line will pay off when Andreas implmentation of
      storing symbol addresses in a seperate file is introduced.
