'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

The RCU fix is a revert for an optimization that could cause deadlocks.

are not covered yet) - the resulting additional fixes are still WIP and
Ingo did not want to delay these pending fixes. See this thread on

If a seccomp filter program is installed, older static binaries and
distributions with older libc implementations (glibc 2.13 and earlier)
that rely on vsyscall use will be terminated regardless of the filter
program policy when executing time, gettimeofday, or getcpu. This is
only the case when vsyscall emulation is in use (vsyscall=emulate is the
default).
This patch emulates system call entry inside a vsyscall=emulate by
populating regs->ax and regs->orig_ax with the system call number prior
to calling into seccomp such that all seccomp-dependencies function
normally. Additionally, system call return behavior is emulated in line
with other vsyscall entrypoints for the trace/trap cases.

Properly define the CAMIF interrupt resources. This device have two
interrupts - corresponding to the "codec" and "preview" data paths.
IRQ_CAM is handled internally by the architecture and demultiplexed
to IRQ_S3C2440_CAM_C and IRQ_S3C2440_CAM_P - these interrupts only
should be handled in the driver.

Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to
inactive domains') introduced possibility to add devices to inactive
power domains and added pm_genpd_dev_need_restore() function which lets
platform core to notify power domain core that the specified device must
be restored (with its runtime_resume() callback) before first use.
This patch adds the pm_genpd_dev_need_restore() call what brings back
the suspend/resume behaviour for the client devices known from the
previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM:
EXYNOS: Hook up power domains to generic power domain infrastructure').
Client device drivers relay on that suspend/resume behaviour, thus this
patch fixes runtime pm operation for client devices.

Move the static inline function setup_jiffies_interrupt() from
<asm/timex.h> to arch/mn10300/kernel/cevt-mn10300.c, which is its only
callsite.
This allows to remove the inclusion of <asm/hardirq.h> and <linux/irq.h>
from <asm/timex.h> and <unit/timex.h>, fixing include hell like:
include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
include/linux/jiffies.h:46:42: error: division by zero in #if
...
make[4]: *** [arch/mn10300/kernel/asm-offsets.s] Error 1
and (after a quick hack for the above by defining CLOCK_TICK_RATE in
<linux/jiffies.h>):

As a consequence, we do need a few more inclusions of <asm/irq.h>, namely

arch/mn10300/unit-asb2305/unit-init.c.

Pull GPIO fixes from Linus Walleij:
"Yes, this is a *LATE* GPIO pull request with fixes for v3.5.
Grant moved across the planet and accidentally fell off the grid, so
he asked me to take over the GPIO merges for a while 10 days ago.
Since then I went over the archives and collected this pile of fixes,
and pulled two of them from the TI maintainer Kevin Hilman. Then
waited for them to at least hit linux-next once or twice."
GPIO fixes for v3.5:
- Invalid context restore on bank 0 for OMAP driver in runtime
suspend/resume cycle
- Check for NULL platform data in sta-2x11 driver
- Constrain selection of the V1 MSM GPIO driver to applicable platforms
(Kconfig issue)
- Make sure the correct output value is set in the wm8994 driver
- Export devm_gpio_request_one() so it can be used in modules.
Apparently some in-kernel modules can be configured to use this
leading to breakage.
- Check that the GPIO is valid in the lantiq driver
- Fix the flag bits introduced for v3.5, so they don't overlap
- Fix a device tree intialization bug for imx21-compatible devices
- Carry over the OF node to the TPS65910 GPIO chip struct

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren <tony@atomide.com>:
Here is one PM regression fix and a defconfig change to disable
echi-omap because the driver currently causes issues with PM.
This annoys Kevin as it makes it harder for him to validate that
PM is working. The proper fixes for the echi-omap are being
discussed, but looks like it will not be properly working with PM
until in v3.7.

Newer gcc are being a bit blind here (it's pretty obvious we don't
reach the code path using the array if we haven't initialized the
pointer) but none of that is performance critical so let's just
silence it.

There was a typo, checking for CONFIG_TRACE_IRQFLAG instead of
CONFIG_TRACE_IRQFLAGS causing some useful debug code to not be
built
This in turns causes a build error on BookE 64-bit due to incorrect
semicolons at the end of a couple of macros, so let's fix that too

Looks like we still have issues with pSeries and Cell idle code
vs. the lazy irq state. In fact, the reset fixes that went upstream
are exposing the problem more by causing BUG_ON() to trigger (which
this patch turns into a WARN_ON instead).
We need to be careful when using a variant of low power state that
has the side effect of turning interrupts back on, to properly set
all the SW & lazy state to look as if everything is enabled before
we enter the low power state with MSR:EE off as we will return with
MSR:EE on. If not, we have a discrepancy of state which can cause
things to go very wrong later on.
This patch moves the logic into a helper and uses it from the
pseries and cell idle code. The power4/970 idle code already got
things right (in assembly even !) so I'm not touching it. The power7
"bare metal" idle code is subtly different and correct. Remains PA6T
and some hypervisor based Cell platforms which have questionable
code in there, but they are mostly dead platforms so I'll fix them
when I manage to get final answers from the respective maintainers
about how the low power state actually works on them.

The EHCI driver is not stable enough to be enabled by default. In v3.5,
it has at least the following problems:
- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
when no USB devices connected.)
This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.
In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.
