Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non
upstreamed CHT Whiskey Cove PMIC patches.
This is a somewhat minimal version which adds irqchip support and cells
for: ACPI PMIC opregion support, the i2c-controller driving the external
charger irc and the pwrsrc/extcon block.
Further cells can be added in the future if/when drivers are upstreamed
for them.
[The above patch caused a build error on some archetectures]
From: Arnd Bergmann <[email protected]>
I ran into a build error on ARM with a platform that has a non-standard
clk implementation:
drivers/clk/clk.o: In function `clk_disable':
clk.c:(.text.clk_disable+0x0): multiple definition of `clk_disable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_disable+0x0): first defined here
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-omap1/clock.o:clock.c:(.text.clk_enable+0x0): first defined here
The problem is a device driver that uses 'select COMMON_CLK', which is
generally a bad idea: selecting a subsystem should only be done from
a platform, otherwise we run into circular dependencies. The same driver
also selects 'GPIOLIB' and 'I2C', which has a similar effect.
This turns all three into 'depends on', as it should be.
Finally, we can limit the build to x86, unless we are compile testing.

The Crystal Cove PMIC provides an ACPI OPRegion handler, which must be
available before other drivers using it are loaded, which is why
INTEL_SOC_PMIC is a bool.
Just having the driver is not enough, the driver for the i2c-bus must
also be built in, to ensure this, this patch adds a select for it.
This fixes errors like these during boot:
mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA
ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] (20170119/evregion-166)

acpi 80860F14:02: Failed to change power state to D0
While at it this patch also changes the human readable name of the Kconfig
option to make clear the INTEL_SOC_PMIC option selects support for the
Intel Crystal Cove PMIC and documents why this is a bool.

When a CIFS filesystem is mounted with the forcemand option and the
following command is run on it, lockdep warns about a circular locking
dependency between CifsInodeInfo::lock_sem and the inode lock.
while echo foo > hello; do :; done & while touch -c hello; do :; done
cifs_writev() takes the locks in the wrong order, but note that we can't
only flip the order around because it releases the inode lock before the
call to generic_write_sync() while it holds the lock_sem across that
call.
But, AFAICS, there is no need to hold the CifsInodeInfo::lock_sem across
the generic_write_sync() call either, so we can release both the locks
before generic_write_sync(), and change the order.

Pull mnt namespace updates from Eric Biederman:
"A big break-through came during this development cycle as a way was
found to maintain the existing umount -l semantics while allowing for
optimizations that improve the performance. That is represented by the
first change in this series moving the reparenting of mounts into
their own pass. This has allowed addressing the horrific performance
of umount -l on a carefully crafted tree of mounts with locks held
(0.06s vs 60s in my testing). What allowed this was not changing where
umounts propagate to while propgating umounts.
The next change fixes the case where the order of the mount whose
umount are being progated visits a tree where the mounts are stacked
upon each other in another order. This is weird but not hard to
implement.
The final change takes advantage of the unchanging mount propgation
tree to skip parts of the mount propgation tree that have already been
visited. Yielding a very nice speed up in the worst case.
There remains one outstanding question about the semantics of umount -l
that I am still discussiong with Ram Pai. In practice that area of the
semantics was changed by 1064f874abc0 ("mnt: Tuck mounts under others
instead of creating shadow/side mounts.") and no regressions have been
reported. Still I intend to finish talking that out with him to ensure
there is not something a more intense use of mount propagation in the
future will not cause to become significant"

shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
memory and blocks on the shrinker.
These four patches have been well tested. His second set of patches
are still being tested, so I plan to hold them until the next merge
window, after we have more weeks of testing. The first patch
eliminates the flush_delayed_work, which can block.
- Andreas's second patch protects setting of gl_object for rgrps with
a spin_lock to prevent proven races.
- His third patch introduces a centralized mechanism for queueing
glock work with better reference counting, to prevent more races.
-His fourth patch retains a reference to inode glocks when an error
occurs while creating an inode. This keeps the subsequent evict
from needing to reacquire the glock, which might call into DLM and
block in low memory conditions.
- Arvind Yadav has a patch to add const to attribute_group

- I have a patch to detect directory entry inconsistencies and

Don't try to check PageError since that's potentially racy and not
necessarily going to be set after writepage errors out.
Instead, check the mapping for an error after writepage returns. That
should also help us detect errors that occurred if the VM tried to
clean the page earlier due to memory pressure.

There are a couple places where jfs calls write_one_page() where clean
recovery is not possible. In these cases, the file system should be
marked dirty. To do this, it is now necessary to store the superblock in
the metapage structure.

The callers all set it to 1.
Also, make it clear that this function will not set any sort of AS_*
error, and that the caller must do so if necessary. No existing caller
uses this on normal files, so none of them need it.
Also, add __must_check here since, in general, the callers need to handle
an error here in some fashion.

"Continuation of timers-related stuff (there had been more, but my
parts of that series are already merged via timers/core). This is more

unification of native and compat timers-related syscalls"

IPOIB is calling free_rdma_netdev even though alloc_rdma_netdev has
returned -EOPNOTSUPP.
Move free_rdma_netdev from ib_device structure to rdma_netdev structure
thus ensuring proper cleanup function is called for the rdma net device.
Fix the following trace:
