Pull misc vfs updates from Al Viro:
"All kinds of stuff. That probably should've been 5 or 6 separate
branches, but by the time I'd realized how large and mixed that bag
had become it had been too close to -final to play with rebasing.
Some fs/namei.c cleanups there, memdup_user_nul() introduction and
switching open-coded instances, burying long-dead code, whack-a-mole
of various kinds, several new helpers for ->llseek(), assorted
cleanups and fixes from various people, etc.
One piece probably deserves special mention - Neil's
lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets
called without ->i_mutex and tries to avoid ever taking it. That, of
course, means that it's not useful for any directory modifications,
but things like getting inode attributes in nfds readdirplus are fine
with that. I really should've asked for moratorium on lookup-related
changes this cycle, but since I hadn't done that early enough... I
*am* asking for that for the coming cycle, though - I'm going to try
and get conversion of i_mutex to rwsem with ->lookup() done under lock
taken shared.
There will be a patch closer to the end of the window, along the lines
of the one Linus had posted last May - mechanical conversion of
->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
inode_is_locked()/inode_lock_nested(). To quote Linus back then:
-----
| This is an automated patch using
|
| sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
| sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
| sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[ ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
| sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
| sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
|
| with a very few manual fixups
-----
I'm going to send that once the ->i_mutex-affecting stuff in -next
gets mostly merged (or when Linus says he's about to stop taking
merges)"

Pull component updates from Russell King:
"Updates for the component helper merged last year.
This update removes the old add_components method of detecting and
looking up the components associated with a master device. Last time
I checked during the 4.4-rc cycle, there were no users of the old
interfaces, as has been the case for some time now. Breakage due to
conflicting development is possible, in which case this pull will have
to be reverted - however, these changes have been in linux-next since
Dec 7th without any problems reported.
Removal of that then allows us to change the way we track components
internally, allowing us to release data that has been used for
matching at the appropriate time, thereby allowing any resource leaks
caused by that missing functionality to be resolved"

Pull arm[64] perf updates from Will Deacon:
"In the past, I have funnelled perf updates through the respective
architecture trees, but now that the arm/arm64 perf driver has been
largely consolidated under drivers/perf/, it makes more sense to send
a separate pull, particularly as I'm listed as maintainer for all the
files involved. I offered the branch to arm-soc, but Arnd suggested
that I just send it to you directly.
So, here is the arm/arm64 perf queue for 4.5. The main features are
described below, but the most useful change is from Drew, which
advertises our architected event mapping in sysfs so that the perf
tool is a lot more user friendly and no longer requires the use of
magic hex constants for profiling common events.
- Support for the CPU PMU in Cortex-A72
- Add sysfs entries to describe the architected events and their
mappings for PMUv{1-3}"

Pull arm64 updates from Will Deacon:
"Here is the core arm64 queue for 4.5. As you might expect, the
Christmas break resulted in a number of patches not making the final
cut, so 4.6 is likely to be larger than usual. There's still some
useful stuff here, however, and it's detailed below.
The EFI changes have been Reviewed-by Matt and the memblock change got
an "OK" from akpm.
Summary:
- Support for a separate IRQ stack, although we haven't reduced the
size of our thread stack just yet since we don't have enough data
to determine a safe value
- Refactoring of our EFI initialisation and runtime code into
drivers/firmware/efi/ so that it can be reused by arch/arm/.
- Ftrace improvements when unwinding in the function graph tracer
- Document our silicon errata handling process
- Cache flushing optimisation when mapping executable pages
- Support for hugetlb mappings using the contiguous hint in the pte"

Pull device mapper updates from Mike Snitzer:
- The most significant set of changes this cycle is the Forward Error
Correction (FEC) support that has been added to the DM verity target.
Google uses DM verity on all Android devices and it is believed that
this FEC support will enable DM verity to recover from storage
failures seen since DM verity was first deployed as part of Android.
- A stable fix for a race in the destruction of DM thin pool's
workqueue
- A stable fix for hung IO if a DM snapshot copy hit an error
- A few small cleanups in DM core and DM persistent data.
- A couple DM thinp range discard improvements (address atomicity of
finding a range and the efficiency of discarding a partially mapped
thin device)
- Add ability to debug DM bufio leaks by recording stack trace when a
buffer is allocated. Upon detected leak the recorded stack is
dumped.

Pull regmap updates from Mark Brown:
"There's no real overall theme to the regmap changes for this release,
it's a collection of individual features. The main bits are:
- Support for 64 bit registers, mainly for MMIO use, from Xiubo Li.
- Support for trigger type configuration for regmap-irq from Laxman
Dewangan.
- Use native physical I/O for MMIO register maps to avoid confusion
with the conversions that readl() and writel() do to little endian
on big endian systems (with some DT updates to fix some workarounds
people were doing), code from Simon Arlott.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control patches for the v4.5 series.
Notably I have a patch to driver core from Stephen Boyd in the pull
request, this has been ACKed by Greg so it should be OK. The internal
API needed some tweaking to allow modular Qualcomm pin controllers.
There is a bit of development history in here but it should all add up
nicely and has boiled in linux-next. For example I merged in v4.4-rc5
to get rid of some nasty merge conflicts.
Summary:
- New drivers:
- PXA2xx pin controller support
- Broadcom NSP pin controller support
- New subdrivers:
- Samsung EXYNOS5410 support
- Qualcomm MSM8996 support
- Qualcomm PM8994 support
- Qualcomm PM8994 MPP support
- Allwinner sunxi H3 support
- Allwinner sunxi A80 support
- Rockchip RK3228 support
- Rename the Cygnus pinctrl driver to "iproc" as it is more generic
than was originally thought.
- A bunch of Lantiq/Xway updates especially from the OpenWRT people.
- Several refactorings for the Super-H SH PFC pin controllers.
Adding SCIF_CLK support.
- Several fixes to the Atlas 7 driver.
- Various fixes all over the place"

In case the PEB was never used it can be put back on the free list
saving a precious erase cycle.

- to_leb_clean -> dst_leb_clean
- use the nested option for ensure_wear_leveling()
- do_sync_erase() can't go -ENOMEM so we can just go into

When there is an error copying a chunk dm-snapshot can incorrectly hold
associated bios indefinitely, resulting in hung IO.
The function copy_callback sets pe->error if there was error copying the
chunk, and then calls complete_exception. complete_exception calls
pending_complete on error, otherwise it calls commit_exception with
commit_callback (and commit_callback calls complete_exception).
The persistent exception store (dm-snap-persistent.c) assumes that calls
to prepare_exception and commit_exception are paired.
persistent_prepare_exception increases ps->pending_count and
persistent_commit_exception decreases it.
If there is a copy error, persistent_prepare_exception is called but
persistent_commit_exception is not. This results in the variable
ps->pending_count never returning to zero and that causes some pending
exceptions (and their associated bios) to be held forever.
Fix this by unconditionally calling commit_exception regardless of
whether the copy was successful. A new "valid" parameter is added to
commit_exception -- when the copy fails this parameter is set to zero so
that the chunk that failed to copy (and all following chunks) is not
recorded in the snapshot store. Also, remove commit_callback now that
it is merely a wrapper around pending_complete.

The link resume logic uses a 200msec delay while debouncing
the SControl register. The rationale behind that delay is
to accommodate some PHYs that behave badly if their SStatus/
SControl registers are pounded immediately on resume.
The Broadcom STB SATA PHY does not seem to have this issue.
This patch introduces a new link flag that allows platforms
to skip the debounce delay if it isn't needed.

sleeps (<20 ms)
Since msleep() may sleep longer than intended time for values less
than 20ms, this patch allows the use of usleep_range for waits less
that 20ms. usleep_range is a finer precision implementation of
msleep and is designed to be a drop-in replacement for udelay
where a precise sleep/busy-wait is unnecessary.
More details can be found at http://lkml.org/lkml/2007/8/3/250
and in Documentation/timers/timers-howto.txt.
This change has been done to improve the performace in PIO6 mode

buffers the driver will use two or more ops if required.
If the ioctl returns 0, the application must check the status of each
segment with the segments status field. If the ioctl returns a -ve
error code (EINVAL or EFAULT), the status of individual ops is
undefined.

When mapping a non-page-aligned scatterlist entry, we copy the original
offset to the output DMA address before aligning it to hand off to
iommu_map_sg(), then later adding the IOVA page address portion to get
the final mapped address. However, when the IOVA page size is smaller
than the CPU page size, it is the offset within the IOVA page we want,
not that within the CPU page, which can easily be larger than an IOVA
page and thus result in an incorrect final address.
Fix the bug by taking only the IOVA-aligned part of the offset as the
basis of the DMA address, not the whole thing.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-next
KVM/ARM changes for Linux v4.5
- Complete rewrite of the arm64 world switch in C, hopefully
paving the way for more sharing with the 32bit code, better
maintainability and easier integration of new features.
Also smaller and slightly faster in some cases...
- Support for 16bit VM identifiers
- Various cleanups

This reverts commit bda7c4c2b9767ce2af4394754498662d62079af5.
These drivers build as modules now that we use
platform_irq_count() instead of of_irq_count().

of_irq_count() is not an exported symbol (and it shouldn't be
used by platform drivers anyway) so use platform_irq_count()
instead. This allows us to make the qcom pinctrl drivers modular
again.

A recent patch added calls to of_irq_count() in the qcom pinctrl
drivers and that caused module build failures because
of_irq_count() is not an exported symbol. We shouldn't export
of_irq_count() to modules because it's an internal OF API that
shouldn't be used by drivers. Platform drivers should use
platform device APIs instead. Therefore, add a platform_irq_count()
API that mirrors the of_irq_count() API so that platform drivers
can stay DT agnostic.
