Power management callbacks defined by SIMPLE_DEV_PM_OPS are only used if
the PM_SLEEP Kconfig symbol has been defined. If not, the compiler will
complain about them being unused.

This bit can be configurable in the platform side.

Dear maintainers,
with kernel 3.5 on debian x86_64 and wpa_supplicant 1.0 on an MSI laptop trying
to start the wireless network adapter, results in a kernel oops:
BUG: unable to handle kernel NULL pointer dereference at 0082
IP: [] net_tx_action+0xd0/0xd0
PGD 392aa067 PUD 390b7067 PMD
Unmuting the analog bypass causes any input to be directly bypassed to
the outputs, which is usually not expected by the user.

Recent changes to the firmware loading helpers cause drivers to stall

Hi Linus,
I would like to ask for pulling a set of fixup patches for ARM
dma-mapping extensions merged in v3.6-rc1.
The following changes since commit 0d7614f09c1ebdbaa1599a5aba7593f147bf96ee:
Linux 3.6-rc1 (2012-08-02 16:38:10 -0700)
with the top-most commit d9e0d149b5dcc2ef4688afc572b9906bc
Do not leak memory by updating pointer with potentially NULL realloc return
value.

Hi,
Yes it used to work with 2.6 kernel.
Ok I will do a bisect and try to find the source of the problem.
I'll notify you if I'll find something but don't expect it to be fast
cause the problem happens on my home laptop (pretty old and rusty :) )
and I also have a lot of other stuff to do.

Hi all,
Changes since 20120807:
Renamed tree: s5p to samsung
The osd tree gained a conflict against the nfs tree.
The tty tree still has its build failures for which I have disabled 2
staging drivers and applied a patch. It lost its conflicts.
I have still reverted 3 commits from the signal t

NFS appears to use d_obtain_alias() to create the root dentry rather
than d_make_root. This can cause 'prepend_path()' to complain that the
root has a weird name if an NFS filesystem is lazily unmounted.
e.g. if "/mnt" is an NFS mount then
{ cd /mnt; umount -l /mnt ; ls -l /proc/self/cwd; }

This patchset updates arch-vt8500 to devicetree and removes all the old-style
code. Support for WM8650 has also been added.
Example dts/dtsi files are given for the three currently supported models.
Major changes:
GPIO code has been converted to a platform_device and rewritten as WM8505
support

Hi,
I ran into a problem on my AMD box whereby I would hit the
WARN_ON_ONCE(cpuctx->cgrp) in perf_cgroup_switch().
It took me a while to track this down. It turns out that the
list_for_each_entry_rcu() loop had multiple iterations. That's
normal, we have CPU PMU and IBS PMU. But what caused
