CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.

"This is the main pull request for block storage for 4.15-rc1.
Nothing out of the ordinary in here, and no API changes or anything
like that. Just various new features for drivers, core changes, etc.
In particular, this pull request contains:
- A patch series from Bart, closing the whole on blk/scsi-mq queue
quescing.
- A series from Christoph, building towards hidden gendisks (for
multipath) and ability to move bio chains around.
- NVMe
- Support for native multipath for NVMe (Christoph).
- Userspace notifications for AENs (Keith).
- Command side-effects support (Keith).
- SGL support (Chaitanya Kulkarni)
- FC fixes and improvements (James Smart)
- Lots of fixes and tweaks (Various)
- bcache
- New maintainer (Michael Lyle)
- Writeback control improvements (Michael)
- Various fixes (Coly, Elena, Eric, Liang, et al)
- lightnvm updates, mostly centered around the pblk interface
(Javier, Hans, and Rakesh).
- Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)
- Writeback series that fix the much discussed hundreds of millions
of sync-all units. This goes all the way, as discussed previously
(me).
- Fix for missing wakeup on writeback timer adjustments (Yafang
Shao).
- Fix laptop mode on blk-mq (me).
- {mq,name} tupple lookup for IO schedulers, allowing us to have
alias names. This means you can use 'deadline' on both !mq and on
mq (where it's called mq-deadline). (me).
- blktrace race fix, oopsing on sg load (me).
- blk-mq optimizations (me).
- Obscure waitqueue race fix for kyber (Omar).
- NBD fixes (Josef).
- Disable writeback throttling by default on bfq, like we do on cfq
(Luca Miccio).
- Series from Ming that enable us to treat flush requests on blk-mq
like any other request. This is a really nice cleanup.
- Series from Ming that improves merging on blk-mq with schedulers,
getting us closer to flipping the switch on scsi-mq again.
- BFQ updates (Paolo).
- blk-mq atomic flags memory ordering fixes (Peter Z).
- Loop cgroup support (Shaohua).
- Lots of minor fixes from lots of different folks, both for core and
driver code"

fill_balloon doing memory allocations under balloon_lock
can cause a deadlock when leak_balloon is called from
virtballoon_oom_notify and tries to take same lock.
To fix, split page allocation and enqueue and do allocations outside the lock.
Here's a detailed analysis of the deadlock by Tetsuo Handa:
In leak_balloon(), mutex_lock(&vb->balloon_lock) is called in order to
serialize against fill_balloon(). But in fill_balloon(),
alloc_page(GFP_HIGHUSER[_MOVABLE] | __GFP_NOMEMALLOC | __GFP_NORETRY) is
called with vb->balloon_lock mutex held. Since GFP_HIGHUSER[_MOVABLE]
implies __GFP_DIRECT_RECLAIM | __GFP_IO | __GFP_FS, despite __GFP_NORETRY
is specified, this allocation attempt might indirectly depend on somebody
else's __GFP_DIRECT_RECLAIM memory allocation. And such indirect
__GFP_DIRECT_RECLAIM memory allocation might call leak_balloon() via
virtballoon_oom_notify() via blocking_notifier_call_chain() callback via
out_of_memory() when it reached __alloc_pages_may_oom() and held oom_lock
mutex. Since vb->balloon_lock mutex is already held by fill_balloon(), it
will cause OOM lockup.
Thread1 Thread2
fill_balloon()
takes a balloon_lock
balloon_page_enqueue()
alloc_page(GFP_HIGHUSER_MOVABLE)
direct reclaim (__GFP_FS context) takes a fs lock
waits for that fs lock alloc_page(GFP_NOFS)
__alloc_pages_may_oom()
takes the oom_lock
out_of_memory()
blocking_notifier_call_chain()
leak_balloon()
tries to take that balloon_lock and deadlocks

patches are basically in three categories: (1) patches related to
broken xfstest cases, (2) patches related to improving iomap and
start using it in GFS2, and (3) general typos and clarifications.
Please note that one of the iomap patches extends beyond GFS2 and
affects other file systems, but it was publically reviewed by a
variety of file system people in the community.
1. Andreas has a patch that simply renames variable 'bsize' to 'factor'
to clarify the logic related to gfs2_block_map.
2. He also has a patch to correctly set ctime in the setflags ioctl,
which fixes broken xfstests test 277.
3. He also fixed broken xfstest 258, due to an atime initialization
problem.
4. He also fixed broken xfstest 307, in which GFS2 was not setting
ctime when setting acls.
5. He has a patch to switch general iomap code from blkno to disk
offset for a variety of file systems.
6. He has a patch to add a new IOMAP_F_DATA_INLINE flag for iomap
to indicate blocks that have data mixed with metadata.
7. I contributed a patch to make inode height info part of the
'metapath' data structure to facilitate using iomap in GFS2.
8. I have a patch to start using iomap inside GFS2 and switch GFS2's
block_map functions to use iomap under the covers.
9. I have a patch to switch GFS2's fiemap implementation from using
block_map to using iomap under the covers.
10. Andreas has a patch to implement SEEK_HOLE and SEEK_DATA via
iomap in GFS2.
11. I have a patch related to journaled data pages not being properly
synced to media when writing inodes. This was caught with xfstests.
12. I have a patch to fix another failing xfstest case in which
switching a file from ordered_write to journaled data via set_flags
caused a deadlock.
13. Andreas has a patch to fix failing xfstest case 066, which was
due to not properly syncing dirty inodes when changing extended
attributes.
14. Andreas fixed a minor typo in a comment.
15. Andreas contributed a patch to partially fix xfstest 424, which
involved GET_FLAGS and SET_FLAGS ioctl. This is also a cleanup
and simplification of the translation of flags from fs flags to
gfs2 flags.
16. He also added support for STATX_ATTR_ in statx, which fixed broken
xfstest 424.
17. He also contributed a fix for failing xfstest 093 which fixes a
recursive glock problem with gfs2_xattr_get and _set.

Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd atomisp
cleanups (take the media tree's version).

Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.
Specifics:
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to
support power management driver flags allowing device drivers to

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

Pull irq core updates from Thomas Gleixner:
"A rather large update for the interrupt core code and the irq chip drivers:
- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate
pull request. This allows to replace the convoluted nested loop
allocation function in x86 with a facility which supports the
recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.
- A large update to the ARM GIC-V3-ITS driver adding support for
range selectors.
- New interrupt controllers:
- Meson and Meson8 GPIO
- BCM7271 L2
- Socionext EXIU
If you expected that this will stop at some point, I have to
disappoint you. There are new ones posted already. Sigh!
- STM32 interrupt controller support for new platforms.

Pull core locking updates from Ingo Molnar:
"The main changes in this cycle are:
- Another attempt at enabling cross-release lockdep dependency
tracking (automatically part of CONFIG_PROVE_LOCKING=y), this time
with better performance and fewer false positives. (Byungchul Park)
- Introduce lockdep_assert_irqs_enabled()/disabled() and convert
open-coded equivalents to lockdep variants. (Frederic Weisbecker)
- Add down_read_killable() and use it in the VFS's iterate_dir()
method. (Kirill Tkhai)
- Convert remaining uses of ACCESS_ONCE() to
READ_ONCE()/WRITE_ONCE(). Most of the conversion was Coccinelle
driven. (Mark Rutland, Paul E. McKenney)
- Get rid of lockless_dereference(), by strengthening Alpha atomics,
strengthening READ_ONCE() with smp_read_barrier_depends() and thus
being able to convert users of lockless_dereference() to
READ_ONCE(). (Will Deacon)
- Various micro-optimizations:
- better PV qspinlocks (Waiman Long),
- better x86 barriers (Michael S. Tsirkin)
- better x86 refcounts (Kees Cook)
- ... plus other fixes and enhancements. (Borislav Petkov, Juergen

As reported by kernelci and other build bots, we now get a link
failure without CONFIG_KALLSYMS:
module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value'
This adds a dummy helper with the same name that can be used
for compilation. It's not entirely clear to me what this
should return for !CONFIG_KALLSYMS, I picked an unconditional
'false', which leads to the module address being unavailable
to user space.

Building kallsyms fails without CONFIG_PRINTK due to a missing

kernel/kallsyms.c:670:10: error: 'kptr_restrict' undeclared (first use in this function); did you mean 'keyring_restrict'?

After several quiet kernel releases we've got a couple of new features
in regmap, support for using hwspinlocks as the lock for the internal
data structures and a helper for polling on regmap_fields. The Kconfig
dependencies on hwspinlocks were annoyingly difficult to squash between
things behaving surprisingly and randconfig, I could've squashed those
commits down but might've have caused hassle with other trees trying to
use the new support.
- Support for using a hwspinlock to protect the regmap.
- An iopoll style helper for regmap_field.
