Pavel Machek 69fd8d2467 drivers/video/msm: update to new kernel
TASK_INTERRUPTIBLE and friends are now only available after including
<linux/sched.h>, so include it when needed.

bus_id is no longer available/necessary, so remove that.

Android pmem driver is not available in mainline, so remove its hooks
from drivers/video.

Sergei Shtylyov d62668e1dd gpiolib: fix device_create() result check
In case of failure, device_create() returns not NULL but the error code.
The current code checks for non-NULL though which causes kernel oops in
sysfs_create_group() when device_create() fails.  Check for error using
IS_ERR() and propagate the error value using PTR_ERR() instead of fixed
-ENODEV code returned now...

Scott Valentine bcb3a1676b rtc: v3020: fix v3020_mmio_read_bit()
v3020_mmio_read_bit() always returns 0 when left_shift > 7.

v3020_mmio_read_bit()'s return type is (unsigned char).  The code returns
a value masked by (1 << left_shift) that is casted to the return type.  If
left_shift is larger than 7, the cast will always result in a 0 return
value.  The problem was discovered with left_shift = 16, and the included
patch corrects the problem.

The bug was introduced in the last (Apr 3 2009) commit of the file, kernel
versions 2.6.30 and later.

Sukadev Bhattiprolu 29f12ca321 pidns: fix a leak in /proc dentries and inodes with pid namespaces.
Daniel Lezcano reported a leak in 'struct pid' and 'struct pid_namespace'
that is discussed in:

	http://lkml.org/lkml/2009/10/2/159.

To summarize the thread, when container-init is terminated, it sets the
PF_EXITING flag, zaps other processes in the container and waits to reap
them.  As a part of reaping, the container-init should flush any /proc
dentries associated with the processes.  But because the container-init is
itself exiting and the following PF_EXITING check, the dentries are not
flushed, resulting in leak in /proc inodes and dentries.

This fix reverts the commit 7766755a2f ("Fix /proc dcache deadlock
in do_exit") which introduced the check for PF_EXITING.  At the time of
the commit, shrink_dcache_parent() flushed dentries from other filesystems
also and could have caused a deadlock which the commit fixed.  But as
pointed out by Eric Biederman, after commit 0feae5c47a,
shrink_dcache_parent() no longer affects other filesystems.  So reverting
the commit is now safe.

As pointed out by Jan Kara, the leak is not as critical since the
unclaimed space will be reclaimed under memory pressure or by:

	echo 3 > /proc/sys/vm/drop_caches

But since this check is no longer required, its best to remove it.

KAMEZAWA Hiroyuki e00e431612 memcg: fix wrong pointer initialization at page migration when memcg is disabled.
Lee Schermerhorn reported that he saw bad pointer dereference in
mem_cgroup_end_migration() when he disabled memcg by boot option.

memcg's page migration logic works as

	mem_cgroup_prepare_migration(page, &ptr);
	do page migration
	mem_cgroup_end_migration(page, ptr);

Now, ptr is not initialized in prepare_migration when memcg is disabled
by boot option. This causes panic in end_migration. This patch fixes it.

Krzysztof Helt f5c15d0b37 fb: remove fb_save_state() and fb_restore_state operations
Remove fb_save_state() and fb_restore_state operations from frame buffer layer.
They are used only in two drivers:
1. savagefb  - and cause bug #11248
2. uvesafb

Usage of these operations is misunderstood in both drivers so kill these
operations, fix the bug #11248 and avoid confusion in the future.

Tested on Savage 3D/MV card and the patch fixes the bug #11248.

The frame buffer layer uses these funtions during switch between graphics
and text mode of the console, but these drivers saves state before
switching of the frame buffer (in the fb_open) and after releasing it (in
the fb_release).  This defeats the purpose of these operations.

Mel Gorman cc4a685146 page allocator: always wake kswapd when restarting an allocation attempt after direct reclaim failed
If a direct reclaim makes no forward progress, it considers whether it
should go OOM or not.  Whether OOM is triggered or not, it may retry the
allocation afterwards.  In times past, this would always wake kswapd as
well but currently, kswapd is not woken up after direct reclaim fails.
For order-0 allocations, this makes little difference but if there is a
heavy mix of higher-order allocations that direct reclaim is failing for,
it might mean that kswapd is not rewoken for higher orders as much as it
did previously.

This patch wakes up kswapd when an allocation is being retried after a
direct reclaim failure.  It would be expected that kswapd is already
awake, but this has the effect of telling kswapd to reclaim at the higher
order as well.

Anton Vorontsov 8c68e2f788 powerpc/86xx: Add power management support for MPC8610HPCD boards
This patch adds needed nodes and properties to support suspend/resume
on the MPC8610HPCD boards.

There is a dedicated switch (SW9) that is used to wake up the boards.
By default the SW9 button is routed to IRQ8, but could be re-routed
(via PIXIS) to sreset.

With 'no_console_suspend' kernel command line argument specified, the
board is also able to wakeup upon serial port input.

Anton Vorontsov 4ffd6952a0 powerpc/85xx/86xx: Add suspend/resume support
This patch adds suspend/resume support for MPC8540 and MPC8641D-
compatible CPUs. To reach sleep state, we just write the SLP bit
into the PM control and status register.

So far we don't support Deep Sleep mode as found in newer MPC85xx
CPUs (i.e. MPC8536). It can be relatively easy implemented though,
and for it we reserve 'mem' suspend type.

Anton Vorontsov fdfde24e10 powerpc/qe: Implement QE driver for handling resume on MPC85xx

Anton Vorontsov 4c1fba4429 spi_mpc8xxx: Add support for QE DMA mode and CPM1/CPM2 chips
This patch adds QE buffer descriptors mode support for the
spi_mpc8xxx driver, and as a side effect we now support CPM1
and CPM2 SPI controllers.

That means that today we support almost all MPC SPI controllers:

- MPC834x-style controllers (support PIO mode only);
- CPM1 and CPM2 controllers (support DMA mode only);
- QE SPI controllers in CPU mode (PIO mode with shift quirks);
- QE SPI controllers in buffer descriptors (DMA) mode;

The only controller we don't currently support is a newer eSPI
(with a dedicated chip selects and a bit different registers map).

Anton Vorontsov 80952988a2 powerpc/qe&cpm2: Avoid redefinitions in CPM2 and QE headers
struct mcc defined in both immap_qe.h and immap_cpm2.h, so they will
conflic when included in a single file. The mcc struct is easy to deal
with, since it isn't used in any driver (yet), so let's just rename QE
version to qe_mcc.

The ucb_ctlr is a bit trickier, since it is used by fsl_qe_udc driver,
and the driver supports both CPM and QE UDCs, plus the QE version is
used to form a bigger immap struct.

I don't want to touch too much of USB code in this series, so for now
let's just copy most generic version into the common cpm.h header,
later we'll create cpm_usb.h where we'll place common USB structs that
are used by QE/CPM UDC and QE Host drivers (FHCI).

And as for the structs in qe.h and cpm2.h, just prefix them with qe_
and cpm_.

P1020 is another member of Freescale QorIQ series of processors.
It is an e500 based dual core SOC.
Being a scaled down version of P2020 it has following differences from P2020:
- 533MHz - 800MHz core frequency.
- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities(new controller).

From board perspective P1020RDB is same as P2020RDB.

  registers with previously allocated muram offset;
- Remove __init attributes from qe_reset() and cpm_muram_init();

core1 has L2, dma2, eth0, pci1, msi.

MPIC is shared between two cores but each core will protect its
