      PCI Hotplug: Fix small mem leak in IBM Hot Plug Controller Driver · b91aac29
      Jesper Juhl authored 
      In drivers/pci/hotplug/ibmphp_ebda.c::ebda_rsrc_controller(), storage is
allocated with kzalloc() and assigned to 'tmp_slot'.  Then lots of
stuff, like ->flag, ->supported_speed etc is set in tmp_slot.  A bit
further down there's then this test :

  if (!bus_info_ptr1) {
    rc = -ENODEV;
    goto error;
  }

At this point, tmp_slot has not been assigned to anything, so when
erroring-out we want to free it, but nothing at the 'error:' label
free's 'tmp_slot' - and we can't really free 'tmp_slot' at 'error:'
since we may jump to that label later when 'tmp_slot' *has* been used
and we do not want it freed. So, the only sane option left seems to be
to kfree(tmp_slot) just before jumping to the 'error:' label in the one
place where this is what actually makes sense. The following patch does
just that and thus kills off a tiny potential memory leak.

      PCI: rename DECLARE_PCI_DEVICE_TABLE to DEFINE_PCI_DEVICE_TABLE · 8647af71
      Andrew Morton authored 
      a) DECLARE_PCI_DEVICE_TABLE is misnamed.  It is used to *define* tables,
   not to declare them.  It should be called DEFINE_PCI_DEVICE_TABLE.

b) It's lame, anyway.  We could implement any number of such helper
   thingies, but we choose not to.


So I wouldn't go adding code which uses this thing until it has a correct
name, and until we've decided that we actually want to live with it.

      Do not include linux/backing-dev.h twice · 3426fadf

      Don't include linux/backing-dev.h twice in mm/filemap.c, it's pointless.

      Fix waitid si_code regression · 6efcae46
      Roland McGrath authored 
      In commit ee7c82da ("wait_task_stopped:
simplify and fix races with SIGCONT/SIGKILL/untrace"), the magic (short)
cast when storing si_code was lost in wait_task_stopped.  This leaks the
in-kernel CLD_* values that do not match what userland expects.

      [CRYPTO] skcipher: Fix section mismatches · f13ba2f7
      Herbert Xu authored 
      The previous patch to move chainiv and eseqiv into blkcipher created
a section mismatch for the chainiv exit function which was also called
from __init.  This patch removes the __exit marking on it.

      x86_64: make ptrace always sign-extend orig_ax to 64 bits · 84c6f604
      Roland McGrath authored 
      This makes 64-bit ptrace calls setting the 64-bit orig_ax field for a
32-bit task sign-extend the low 32 bits up to 64.  This matches what a
64-bit debugger expects when tracing a 32-bit task.

This follows on my "x86_64 ia32 syscall restart fix".  This didn't
matter until that was fixed.

The debugger ignores or zeros the high half of every register slot it
sets (including the orig_rax pseudo-register) uniformly.  It expects
that the setting of the low 32 bits always has the same meaning as a
32-bit debugger setting those same 32 bits with native 32-bit
facilities.

This never arose before because the syscall restart check never
matched any -ERESTART* values due to lack of sign extension.  Before
that fix, even 32-bit ptrace setting orig_eax to -1 failed to trigger
the restart check anyway.  So this was never noticed as a regression
of 64-bit debuggers vs 32-bit debuggers on the same 64-bit kernel.

[ Changed to just do the sign-extension unconditionally on x86-64,
  since orig_ax is always just a small integer and doesn't need
  the full 64-bit range ]
