Commit 7ea6c6c1 ("Move cper.c from drivers/acpi/apei to
drivers/firmware/efi") results in CONFIG_EFI being enabled even
when the user doesn't want this. Since ACPI APEI used to build
fine without UEFI (and as far as I know also has no functional
depency on it), at least in that case using a reverse dependency
is wrong (and a straight one isn't needed).

Whether the same is true for ACPI_EXTLOG I don't know - if there
is a functional dependency, it should depend on EFI rather than
selecting it. It certainly has (currently) no build dependency.

Adjust Kconfig and build logic so that the bad dependency gets
avoided.

Linux 3.10 changed the timing of how thread_info->flags is touched:

x86: Use generic idle loop
(7d1a941731fabf27e5fb6edbebb79fe856edb4e5)

This caused Intel NHM-EX and WSM-EX servers to experience a large number
of immediate MONITOR/MWAIT break wakeups, which caused cpuidle to demote
from deep C-states to shallow C-states, which caused these platforms
to experience a significant increase in idle power.

Note that this issue was already present before the commit above,
however, it wasn't seen often enough to be noticed in power measurements.

Here we extend an errata workaround from the Core2 EX "Dunnington"
to extend to NHM-EX and WSM-EX, to prevent these immediate
returns from MWAIT, reducing idle power on these platforms.

While only acpi_idle ran on Dunnington, intel_idle
may also run on these two newer systems.
As of today, there are no other models that are known
to need this tweak.

After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.

However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:

This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.

Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.

Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

The r8a7790.dtsi file has four sdhi nodes which the first two have the wrong
resource size for their register block. This causes the sh_modbile_sdhi driver

Akira-san has been reporting rare deadlocks of his machine when running
xfstests test 269 on ext4 filesystem. The problem turned out to be in
ext4_da_reserve_metadata() and ext4_da_reserve_space() which called
ext4_should_retry_alloc() while holding i_data_sem. Since
ext4_should_retry_alloc() can force a transaction commit, this is a
lock ordering violation and leads to deadlocks.

Fix the problem by just removing the retry loops. These functions should
just report ENOSPC to the caller (e.g. ext4_da_write_begin()) and that
function must take care of retrying after dropping all necessary locks.

When configuring a default governor (via CONFIG_CPU_FREQ_DEFAULT_*) with the

example, setting 'CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE' ends up with the

Instead of removing cgroup id right after all the csses have been
offlined, we should do that after csses have been destroyed.

To make sure an invalid css pointer won't be returned after the css
is destroyed, make sure css_from_id() returns NULL in this case.

There are cases where cpufreq_add_dev() may fail for some CPUs
during system resume. With the current code we will still have
sysfs cpufreq files for those CPUs and struct cpufreq_policy
would be already freed for them. Hence any operation on those
sysfs files would result in kernel warnings.

Example of problems resulting from resume errors (from Bjørn Mork):

To fix this, remove those sysfs files or put the associated kobject
in case of such errors. Also, to make it simple, remove the cpufreq
sysfs links from all the CPUs (except for the policy->cpu) during
suspend, as that operation won't result in a loss of sysfs file
permissions and we can create those links during resume just fine.

"A regression showed up that there's a large delay when enabling all

This was tracked down to an addition of a synchronize_sched()
performed when system call tracepoints are unregistered.

The synchronize_sched() is needed between the unregistering of the
system call tracepoint and a deletion of a tracing instance buffer.
But placing the synchronize_sched() in the unreg of *every* system
call tracepoint is a bit overboard. A single synchronize_sched()
before the deletion of the instance is sufficient"

"There's one interseting commit - "libata, freezer: avoid block device

writeback being converted to workqueue some releases ago. The bug has
nothing to do with libata but it's just an workaround which is easy to
backport. After discussion, Rafael and I seem to agree that we don't
really need kernel freezables - both kthread and workqueue. There are
few specific workqueues which constitute PM operations and require
freezing, which will be converted to use workqueue_set_max_active()
instead. All other kernel freezer uses are planned to be removed,
followed by the removal of kthread and workqueue freezer support,
hopefully.

Others are device-specific fixes. The most notable is the addition of
NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
M500 SSDs which otherwise suffers data corruption"

When CONFIG_DEBUG_FORCE_WEAK_PER_CPU or CONFIG_ARCH_NEEDS_WEAK_PER_CPU
is set, DEFINE_PER_CPU() explodes into cryptic series of definitions
to still allow using "static" for percpu variables while keeping all
per-cpu symbols unique in the kernel image which is required for weak
symbols. This ultimately converts the actual symbol to global whether
DEFINE_PER_CPU() is prefixed with static or not.

Unfortunately, the macro forgot to add explicit extern declartion of
the actual symbol ending up defining global symbol without preceding
declaration for static definitions which naturally don't have matching
DECLARE_PER_CPU(). The only ill effect is triggering of the following
warnings.

fs/inode.c:74:8: warning: symbol 'nr_inodes' was not declared. Should it be static?
fs/inode.c:75:8: warning: symbol 'nr_unused' was not declared. Should it be static?

duplicate css free logic in the error path but it will be cleaned up

4178bac ARM: call of_clk_init from default time_init handler

added implicit call to of_clk_init() from default time_init callback,
but it did not change platforms calling it from other callbacks, despite
of not having custom time_init callbacks. This caused double clock
initialization on such platforms, leading to boot failures. An example
of such platform is mach-s3c64xx.

This patch fixes boot failure on s3c64xx by dropping custom init_irq
callback, which had a call to of_clk_init() and moving system reset
initialization to init_machine callback. This allows us to have
clocks initialized properly without a need to have custom init_time or
init_irq callbacks.
