On some platforms, _TMP and _CRT/_HOT/_PSV/_ACx have dependency.
And there is no way for OS to detect this dependency.
commit 9bcb8118965ab4631a65ee0726e6518f75cda6c5 shows us a problem
that _TMP must be evaluate after _CRT/_HOT/_PSV/_ACx, or else
firmware will shutdown the system.
But the machine in https://bugzilla.kernel.org/show_bug.cgi?id=43284
shows us that _PSV would return valid value only if _TMP has been
evaluated once.
With this patch, all of the control methods will be evaluated once,
in the _CRT/_HOT/_PSV/_CRT/_TMP order, before they are actually used.
[rjw: Added a local variable for the handle and modified the loop
slightly.]

Many cpuidle drivers measure their time spent in an idle state by
reading the wallclock time before and after idling and calculating the
difference. This leads to erroneous results when the wallclock time gets
updated by another processor in the meantime, adding that clock
adjustment to the idle state's time counter.
If the clock adjustment was negative, the result is even worse due to an
erroneous cast from int to unsigned long long of the last_residency
variable. The negative 32 bit integer will zero-extend and result in a
forward time jump of roughly four billion milliseconds or 1.3 hours on
the idle state residency counter.
This patch changes all affected cpuidle drivers to either use the
monotonic clock for their measurements or make use of the generic time
measurement wrapper in cpuidle.c, which was already working correctly.
Some superfluous CLIs/STIs in the ACPI code are removed (interrupts
should always already be disabled before entering the idle function, and
not get reenabled until the generic wrapper has performed its second
measurement). It also removes the erroneous cast, making sure that
negative residency values are applied correctly even though they should
not appear anymore.

Fix cpufreq_gov_ondemand to skip CPU where another governor is used.
The bug present itself as NULL pointer access on the mutex_lock() call,
an can be reproduced on an SMP machine by setting the default governor
to anything other than ondemand, setting a single CPU's governor to
ondemand, then changing the sample rate by writing on:

Drivers usually expect that the devices they are supposed to handle
will be operational when their .probe() routines are called, but that
need not be the case on some ACPI-based systems with ACPI-based
device enumeration where the BIOSes don't put devices into D0 by
default. To work around this problem it is sufficient to change
bus type .probe() routines to ensure that devices will be powered
on before the drivers' .probe() routines run (and their .remove()
and .shutdown() routines accordingly).
Modify platform_drv_probe() to run acpi_dev_pm_attach() for devices
whose ACPI handles are present, so that ACPI power management is used
to change their power states. Analogously, modify
platform_drv_remove() and platform_drv_shutdown() to call
acpi_dev_pm_detach() for those devices, so that they are not subject
to ACPI PM any more.

Pull MIPS fixes from Ralf Baechle:
"Three issues fixed accross the field:
- Some functions that were recently outlined as part of a preemption
fix were causing problems with function tracing.
- The recently merged in-kernel MPI library uses very outdated
headers that contain MIPS-specific code which won't build on with
gcc 4.4 or newer.
- The MIPS non-NUMA memory initialization was making only a very
half-baked attempt at merging adjacent memory ranges. This kept
the code simple enough but is now causing issues with kexec."

While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

PM QoS flags have to be handled by dev_pm_qos_constraints_destroy()
in the same way as PM QoS resume latency constraints. That is, if
they have been exposed to user space, they have to be hidden from it
and the list of flags requests has to be flushed before destroying
the device's PM QoS object. Make that happen.

This change was made by commit 8636fd2 (cpufreq: fix jiffies/cputime
mixup in conservative/ondemand governors) before, but then it has
been reverted inadvertently by commit 4471a34 (cpufreq: governors:
remove redundant code).
The changelog of commit 8636fd2's says:
The function get_cpu_idle_time_jiffy in both the conservative and
ondemand governors use jiffies_to_usecs to convert a cputime value
to usecs which gives the wrong value on architectures where cputime
and jiffies use different units. Only matters if NO_HZ is
disabled, since otherwise get_cpu_idle_time_us should already
return a valid value, and get_cpu_idle_time_jiffy isn't actually
called.
Since now we have only one common get_cpu_idle_time_jiffy() used by
both governors in question, modify it along the lines of commit
8636fd2 to restore the correct behavior.

Pull MTD fixes from David Woodhouse:
"The most important part of this is that it fixes a regression in
Samsung NAND chip detection, introduced by some rework which went into
3.7. The initial fix wasn't quite complete, so it's in two parts. In
fact the first part is committed twice (Artem committed his own copy
of the same patch) and I've merged Artem's tree into mine which
already had that fix.
I'd have recommitted that to make it somewhat cleaner, but figured by
this point in the release cycle it was better to merge *exactly* the
commits which have been in linux-next.
If I'd recommitted, I'd also omit the sparse warning fix. But it's
there, and it's harmless — just marking one function as 'static' in
onenand code.
This also includes a couple more fixes for stable: an AB-BA deadlock
in JFFS2, and an invalid range check in slram."

This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.
The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.
This fix takes the same approach as 0bce04b that solved the equivalent problem
for of_address_to_resource.

"The highlight of this update is the fixes for ASoC kirkwood by
Russell. In addition to that, a couple of regression fixes for
HD-audio due to the runtime PM support on 3.7, and other driver-
specific regression fixes like USB MIDI on non-standard USB audio
drivers."

Pull networkign fixes from David Miller:
"Networking bug fixes, Cacio e Pepe edition:
1) BNX2X accidently accesses chip rev specific registers without an
appropriate guard, fix from Ariel Elior.
2) When we removed the routing cache, we set ip_rt_max_size to ~0 just
to keep reporting a value to userspace via sysfs. But the ipv4
IPSEC layer was using this to tune itself which is completely bogus
to now do. Fix from Steffen Klassert.
3) Missing initialization in netfilter ipset code from Jozsef
Kadlecsik.
4) Check CTA_TIMEOUT_NAME length properly in netfilter cttimeout code,
fix from Florian Westphal.
5) After removing the routing cache, we inadvertantly are caching
multicast routes that end up looping back locally, we cannot do
that legitimately any more. Fix from Julian Anastasov.
6) Revert a race fix for 8139cp qemu/kvm that doesn't actually work
properly on real hardware. From Francois Romieu.
7) Fixup errors in example command lines in VXLAN device docs."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
bnx2x: remove redundant warning log
vxlan: fix command usage in its doc
8139cp: revert "set ring address before enabling receiver"

netfilter: cttimeout: fix buffer overflow
netfilter: ipset: Fix range bug in hash:ip,port,net

Make pnpacpi_add_device() ignore ACPI device nodes already associated
with struct device objects representing physical devices.
In particular, this will prevent PNP device objects from being
created for ACPI device nodes already associated with platform
devices.
This change was originally proposed by Mika Westerberg.

dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.
