      [PATCH] s390: fix in-user atomic futex operation. · bafe00cc
      由 Martin Schwidefsky 提交于 
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>

__futex_atomic_op needs to do an atomic operation in the user address space,
not the kernel address space.  Add the missing sacf 256/sacf 0 to switch to
the secondary mode before doing the compare-and-swap.  In addition add
another fixup for catch specification exceptions if the compare-and-swap
address is not aligned.

      [PATCH] elevator switching race · bc1c1169
      由 Jens Axboe 提交于 
      There's a race between shutting down one io scheduler and firing up the
next, in which a new io could enter and cause the io scheduler to be
invoked with bad or NULL data.

To fix this, we need to maintain the queue lock for a bit longer.
Unfortunately we cannot do that, since the elevator init requires to be
run without the lock held.  This isn't easily fixable, without also
changing the mempool API.  So split the initialization into two parts,
and alloc-init operation and an attach operation.  Then we can
preallocate the io scheduler and related structures, and run the attach
inside the lock after we detach the old one.

This patch has survived 30 minutes of 1 second io scheduler switching
with a very busy io load.

      [PATCH] Fix mempolicy.h build error · 45b35a5c
      由 Ralf Baechle 提交于 
      From: Ralf Baechle <ralf@linux-mips.org>

<linux/mempolicy.h> uses struct mm_struct and relies on a definition or
declaration somehow magically being dragged in which may result in a
build:

[...]
  CC      mm/mempolicy.o
In file included from mm/mempolicy.c:69:
include/linux/mempolicy.h:150: warning: ‘struct mm_struct’ declared inside parameter list
include/linux/mempolicy.h:150: warning: its scope is only this definition or declaration, which is probably not what you want

make[1]: *** [mm/mempolicy.o] Error 1
make: *** [mm] Error 2
[ralf@denk linux-ip35]$

Including <linux/sched.h> is a step into direction of include hell so
fixed by adding a forward declaration of struct mm_struct instead.

      [ARM] 3547/1: PXA-OHCI: Allow platforms to specify a power budget · 0c27c5d5
      由 Richard Purdie 提交于 
      Patch from Richard Purdie

Add a power budget variable to the PXA OHCI platform data and add a
default value for the spitz platform(s) which prevents known failures
with certain USB devices.
