036e299180 ARM: dts: i.MX51: Fix OTG PHY clock
Proper clock ID for USB OTG PHY is "usb_phy_gate".
The patch changes this mismatch.

43c9b9e8a4 ARM: imx: set up pllv3 POWER and BYPASS sequentially
Currently, POWER and BYPASS bits are set up in a single write to pllv3
register.  This causes problem occasionally from the IPU/HDMI testing.
Let's follow FSL BSP code to set up POWER bit, relock, and then BYPASS
sequentially.

bc3b84da8a ARM: imx: pllv3 needs relock in .set_rate() call
The pllv3 nees relock not only when powering up but also when rate
changes.  The patch creates a helper function clk_pllv3_wait_lock() and
moves the relock code from clk_pllv3_prepare() into there, so that
both .prepare() and .set_rate() hooks of pllv3 can call into the helper
for relocking.

Since relock is only needed when PLL is powered up while clk_set_rate()
could be called before clk is prepared, we need to add a check in
clk_pllv3_wait_lock() to skip the relock if PLL is not powered.

322503a157 ARM: imx: add sleep for pllv3 relock
The pllv3 relock time varies in the range of 50us ~ 500us, depending on
the specific PLL type, e.g. 50us for ARM PLL and 450us for Audio/Video
PLL.  Let's add a usleep_range() call instead of doing busy wait during
relock.

5d48217210 ARM: imx: v7_cpu_resume() is needed by imx6sl build
Building a kernel with the following options,

  CONFIG_SMP=n
  CONFIG_PM=y
  CONFIG_SOC_IMX6SL=y
  CONFIG_SOC_IMX6Q=n

we will see the build error below.

  arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
  platform-spi_imx.c:(.text+0x2648): undefined reference to `v7_cpu_resume'
  make[1]: *** [vmlinux] Error 1

This is because that v7_cpu_resume() implemented in headsmp.S is also
needed by imx6sl build.  Let's build headsmp.S for CONFIG_SOC_IMX6SL as
well.

2c11b57a8a ARM: imx: improve mxc_restart() on the SRC bit writes
The current comment in the code does not make it clear why the double writes
on SRC bit is needed.  Let's quote the errata to get it clear.  Also, to
ensure there are at least 2 writes happen in the same one 32kHz period,
we actually need 3 writes.  Let's add the third one.

b6e23bb63f ARM: imx: remove imx_src_prepare_restart() call
There is ~10% possibility that the following emergency restart command
fails to reboot imx6q.

$ echo b > /proc/sysrq-trigger

The IMX restart routine mxc_restart() assumes that it will always run on
primary core, and will call imx_src_prepare_restart() to disable
secondary cores in order to get them come to online in the following
boot.  However, the assumption is only true for normal kernel_restart()
case where migrate_to_reboot_cpu() will be called to migrate to primary
core, but not necessarily true for emergency_restart() case.  So when
emergency_restart() calls into mxc_restart() on any secondary core,
system will hang immediately once imx_src_prepare_restart() is called
to disabled secondary cores.  Since emergency_restart() is defined as a
function that is safe to call in interrupt context, we cannot just call
migrate_to_reboot_cpu() to fix the issue.

Fortunately, we just found that the issue can be fixed at imx6q platform
level.  We used to call imx_src_prepare_restart() to disable all
secondary cores before resetting hardware.  Otherwise, the secondary
will fail come to online in the reboot.  However, we recently found that
after commit 6050d18 (ARM: imx: reset core along with enable/disable
operation) comes to play, we do not need to reset the secondary cores
any more.  That said, mxc_restart() now can run on any core to reboot
the system, as long as we remove the imx_src_prepare_restart() call from
mxc_restart().

So let's simply remove imx_src_prepare_restart() call to fix the above
emergency restart failure.

f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

c9aeb249bf Input: ti_am335x_tsc - fix spelling mistake in TSC/ADC DT binding
There was a spelling mistake on TSC/ADC binding where "coordinate" was
spelled as "coordiante".

We can't simply fix the error due to DT being an ABI, the approach taken
was to first use correct spelling and if that fails, fall back to
miss-spelled version.

It's unfortunate that has creeped into the tree.

d5aabbcaee ARM: SoC board updates for 3.13
Board-related updates. This branch is getting smaller and smaller, which is
 the whole idea so that's reassuring.
 
 Right now by far most of the code is related to shmobile updates, and
 they are now switching over to removal of board code and migration to
 multiplatform, so we'll see their board code base shrink in the near
 future too, I hope.
 
 In addition to that is some defconfig updates, some display updates for OMAP
 and a bit of new board support for Rockchip boards.

aac59e3efc ARM: SoC platform changes for 3.13
New and updated SoC support. Among the things new for this release are:
 
 - More support for the AM33xx platforms from TI
 - Tegra 124 support, and some updates to older tegra families as well
 - imx cleanups and updates across the board
 - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
   and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
 - A whole bunch of updates and fixes for integrator, making the platform code
   more modern and switches over to DT-only booting.
 - Support for two new Renesas shmobile chipsets. Next up for them is more work
   on consolidation instead of introduction of new non-multiplatform SoCs, we're
   all looking forward to that!
 - Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

21604cdcdc ARM: SoC cleanups for 3.13
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the
 board, etc.

237f12337c ARM: 7866/1: include: asm: use 'long long' instead of 'u64' within atomic.h
atomic* value is signed value, and atomic* functions need also process
signed value (parameter value, and return value), so 32-bit arm need
use 'long long' instead of 'u64'.

After replacement, it will also fix a bug for atomic64_add_negative():
"u64 is never less than 0".

The modifications are:

  in vim, use "1,% s/\<u64\>/long long/g" command.
  remove '__aligned(8)' which is useless for 64-bit.
  be sure of 80 column limitation after replacement.

c682e51dbc ARM: 7887/1: Don't smp_cross_call() on UP devices in arch_irq_work_raise()
If we're running a kernel compiled with SMP_ON_UP=y and the
hardware only supports UP operation there isn't any
smp_cross_call function assigned. Unfortunately, we call
smp_cross_call() unconditionally in arch_irq_work_raise() and
crash the kernel on UP devices. Check to make sure we're running
on an SMP device before calling smp_cross_call() here.

d34603b07c x86, trace: Add page fault tracepoints
This patch introduces page fault tracepoints to x86 architecture
by switching IDT.

  Two events, for user and kernel spaces, are introduced at the beginning
  of page fault handler for tracing.

  - User space event
    There is a request of page fault event for user space as below.

    https://lkml.kernel.org/r/1368079520-11015-2-git-send-email-fdeslaur+()+gmail+!+com
    https://lkml.kernel.org/r/1368079520-11015-1-git-send-email-fdeslaur+()+gmail+!+com

  - Kernel space event:
    When we measure an overhead in kernel space for investigating performance
    issues, we can check if it comes from the page fault events.

Currently irq vector handlers for tracing are registered in both set_intr_gate()

But, we don't need to do that twice.
So, let's delete __trace_alloc_intr_gate().

commit 6efa20e49b
("xen: Support 64-bit PV guest receiving NMIs") and
commit cd9151e26d
( "xen/balloon: set a mapping for ballooned out pages")
added new instances of __cpuinit usage.

We removed this a couple versions ago; we now want to remove
the compat no-op stubs.  Introducing new users is not what
we want to see at this point in time, as it will break once
the stubs are gone.
