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.

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.
Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

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.

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.

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.

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 6050d181 (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.

 "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

Pull perf/ftrace fix from Steven Rostedt:
 "Dave Jones's trinity program was able to enable the function tracer
  from a normal user account via the perf syscall "perf_event_open()".
  When I was able to reproduce it with trinity, I was able to track down
  exactly how it happened.

  I discovered that the check for whether the function tracepoint should
  be activated or not was using the "perf_paranoid_kernel()" check which
  by default, lets the user continue.  The user should not by default be
  able to enable function tracing.

  The fix is to use "perf_paranoid_tracepoint_raw()" which will not let
  the user enable function tracing.  This is a security fix as normal
  users should never be allowed to enable the function tracer"

Pull s390 updates from Martin Schwidefsky:
 "The bulk of the patches for the 3.13 merge window.

  Heiko spent quite a bit of work to improve the code generation for the
  kernel.  That includes the exploitation of the interlocked-access
  facility for the atomics and bitops implementation and the improvement
  for the -march and -mtune compiler settings.

  Another important change is the removal of the user_mode=home option,
  user processes now always run in primary space.  The storage keys are
  not initialized at system startup any more, with that the storage key
  removal work is complete.  For the PCI support the hibernation hooks
  have been implemented.

  And as usual cleanup and fixes"

New defconfigs which should be able to boot on any 32/64bit machine.
Many drivers are selected to be compiled-in to avoid the need for an
additional initrd and still being able to boot.

STI text console (sticon) was broken on 64bit machines with more than
4GB RAM and this lead in some cases to a kernel crash.

Since sticon uses the 32bit STI API it needs to keep pointers to memory
below 4GB. But on a 64bit kernel some memory regions (e.g. the kernel
stack) might be above 4GB which then may crash the kernel in the STI
functions.

Additionally sticon didn't selected the built-in framebuffer fonts by
default. This is now fixed.

On a side-note: Theoretically we could enhance the sticon driver to
use the 64bit STI API. But - beside the fact that some machines don't
provide a 64bit STI ROM - this would just add complexity.

Clean up code to send correct signal on invalid memory accesses:
Send SIGBUS instead of SIGSEGV for memory accesses outside of mmap'ed
areas

Up to now PA-RISC could live with a trivial version of access_ok().
Our fault handlers can correctly handle fault cases.

But testcases showed that we need a better access check else we won't
always return correct errno failure codes to userspace.

Problem showed up during 32bit userspace tests in which writev() used a
32bit memory area and length which would then wrap around on 64bit
kernel.

In case we fail to power up other CPUs in a SMP system, the kernel
currently shows a wrong number of online CPUs. This change makes the
output more verbose on how many of the CPUs are online. Example:

CPU(s): 1 out of 2 PA8800 (Mako) at 900.000000 MHz online.

The number of IPI calls is already visible as per-cpu IPI irq counters
in/proc/cpuinfo, so let's drop this additional counting.

Each CPU has it's own Control Register 16 (CR16) which is used as time source
for the udelay() function. But since the CR16 registers across different CPUs
are not synced, we need to recalculate the loop count if we get switched away
to ensure that we really delay as much time as requested.

Install targets (install, zinstall, uinstall) on parisc have a
dependency to vmlinux. This may cause parts of the kernel to be rebuilt
during installation. We must avoid this since this may run as root.
Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus
emphasized this in:

http://lkml.org/lkml/2013/7/10/600

So on parisc and maybe other archs we need the same as for x86:

Provide a macro ASM_EXCEPTIONTABLE_ENTRY() to create exception table
entries and convert all open-coded places to use that macro.

This patch is a first step toward creating a exception table which only
holds 32bit pointers even on a 64bit kernel. That way in my own kernel
I was able to reduce the in-kernel exception table from 44kB to 22kB.

The non-IPI interrupts are displayed only for the online cpus from
show_interrupts in kernel/irq/proc.c before calling arch_show_interrupts().
As a result, the column headers and the IPI count don't match if any
CPU is offline.

This patch fixes show_ipi_list to display IPIs for online CPUs only.

This reverts commit cb26a311.

It mysteriously causes NetworkManager to not find the wireless device
for me.  As far as I can tell, Tejun *meant* for this commit to not make
any semantic changes, but there clearly are some.  So revert it, taking
into account some of the calling convention changes that happened in
this area in subsequent commits.
