pinctrl: stm32: add IRQ_DOMAIN_HIERARCHY dependency
The newly added irqchip support for the stm32 pinctrl driver uses
hierarchical IRQ domains as provided by the NVIC primary irqchip.
This works great for any configuration that may be relevant on
stm32, but when doing compile-testing (randconfig), we can
enable it without NVIC or any other primary irqchip that
enables IRQ_DOMAIN_HIERARCHY:
drivers/pinctrl/stm32/pinctrl-stm32.c:212:13: error: 'irq_chip_eoi_parent' undeclared here (not in a function)

This adds a Kconfig dependency to limit compile-testing to
configurations that have IRQ_DOMAIN_HIERARCHY already enabled.
It's not obvious whether we should use 'depends on' or 'select'
here, I think either one works, with 'depends on' being more
intuitive, while 'select' would be less likely to cause dependency
loops.

gpio: mxc: shift gpio_mxc_init() to subsys_initcall level
In general situation on-SoC GPIO controller drivers should be probed
after pinctrl/pinmux controller driver, because on-SoC GPIOs utilize a
pin/pad as a resource provided and controlled by pinctrl subsystem.
This is stated in multiple places, e.g. from drivers/Makefile:
GPIO must come after pinctrl as gpios may need to mux pins etc
Looking at Freescale iMX SoC series specifics, imx*_pinctrl_init()
functions are called at arch_initcall and postcore_initcall init
levels, so the change of initcall level for gpio-mxc driver from
postcore_initcall to subsys_initcall level is sufficient. Also note
that the most of GPIO controller drivers settled at subsys_initcall
level.
If pinctrl subsystem manages pads with GPIO functions, the change is
needed to avoid unwanted driver probe deferrals during kernel boot.

As a practical example on GPIO request a pad function should be

connection between shared pinctrl-imx and pinctrl/pinmux core, namely

the BIOS,when the LevelTrig is Edge and activeLevel is HIGH, to configure
the GPIO registers. Ignore the settings from client.

pinctrl: Add core support for Aspeed SoCs
The Aspeed SoCs typically provide more than 200 pins for GPIO and other
functions. The signal enabled on a pin is determined on a priority
basis, where a given pin can provide a number of different signal types.
In addition to the priority levels, the Aspeed pin controllers describe
the signal active on a pin by compound logical expressions involving
multiple operators, registers and bits. Some difficulty arises as a
pin's function bit masks for each priority level are frequently not the
same (i.e. we cannot just flip a bit to change from a high to low
priority signal), or even in the same register(s). Some configuration
bits affect multiple pins, while in other cases the signals for a bus
must each be enabled individually.
Together, these features give rise to some complexity in the
implementation. A more complete description of the complexities is
provided in the associated header file.
The patch doesn't implement pinctrl/pinmux/pinconf for any particular
Aspeed SoC, rather it adds the framework for defining pinmux
configurations.

block: rename bio bi_rw to bi_opf
Since commit
63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

block/mm: make bdev_ops->rw_page() take a bool for read/write
Commit
abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

Pull more xfs updates from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle, and
contains the new reverse block mapping feature for XFS.
Reverse mapping allows us to track the owner of a specific block on
disk precisely. It is implemented as a set of btrees (one per
allocation group) that track the owners of allocated extents.
Effectively it is a "used space tree" that is updated when we allocate
or free extents. i.e. it is coherent with the free space btrees we
already maintain and never overlaps with them.
This reverse mapping infrastructure is the building block of several
upcoming features - reflink, copy-on-write data, dedupe, online
metadata and data scrubbing, highly accurate bad sector/data loss
reporting to users, and significantly improved reconstruction of
damaged and corrupted filesystems. There's a lot of new stuff coming
along in the next couple of cycles,a nd it all builds in the rmap
infrastructure.
As such, it's a huge chunk of new code with new on-disk format
features and internal infrastructure. It warns at mount time as an
experimental feature and that it may eat data (as we do with all new
on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time kernel
with this code in it is released.
The new rmap enabled code regresses 3 xfstests - all are ENOSPC
related corner cases, one of which Darrick posted a fix for a few
hours ago. The other two are fixed by infrastructure that is part of
the upcoming reflink patchset. This new ENOSPC infrastructure
requires a on-disk format tweak required to keep mount times in
check - we need to keep an on-disk count of allocated rmapbt blocks so
we don't have to scan the entire btrees at mount time to count them.
This is currently being tested and will be part of the fixes sent in
the next week or two so users will not be exposed to this change"

Merge tag 'dm-4.8-fixes' of git://git./linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer:
- a stable dm-flakey fix to error read IO during the 'down_interval'
- a DM core suspend fix to establish the SUSPENDED flag before dropping
the SUSPENDING flag
- a blk-mq request-based DM (dm-mq) dm_stop_queue() fix to properly
stop the blk-mq hw_queues (and cancel pending requeue work); also
set/clear QUEUE_FLAG_STOPPED when stopping/starting the dm-mq
request_queue.
- a DM multipath fix to harden locking of in-core state flags in the
face of concurrent access while handling path failures under heavy
IO.
- a few small DM raid fixes to edge cases caught with further testing.

Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"Here's the second round of block updates for this merge window.
It's a mix of fixes for changes that went in previously in this round,
and fixes in general. This pull request contains:
- Fixes for loop from Christoph
- A bdi vs gendisk lifetime fix from Dan, worth two cookies.
- A blk-mq timeout fix, when on frozen queues. From Gabriel.
- Writeback fix from Jan, ensuring that __writeback_single_inode()
does the right thing.
- Fix for bio->bi_rw usage in f2fs from me.
- Error path deadlock fix in blk-mq sysfs registration from me.
- Floppy O_ACCMODE fix from Jiri.
- Fix to the new bio op methods from Mike.
One more followup will be coming here, ensuring that we don't
propagate the block types outside of block. That, and a rename of
bio->bi_rw is coming right after -rc1 is cut.
- Various little fixes"

Pull more ACPI updates from Rafael Wysocki:
"Two more fixes in ACPI drivers, one in the ACPI EC driver
(stable-candidate) and one in the ACPI button driver.
Specifics:
- An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's
method reentrancy limit to be exceeded for a _Qxx method due to a
large number of concurrent EC operations, so prevent that from
happening by moving the EC handling into a separate workqueue with
a limit on the number of concurrently executed work items (Lv
Zheng)
- Fix the cleanup code in the ACPI button driver that forgets to
clear two variables on exit which causes an error to occur on the
next attmpt to load the driver (Benjamin Tissoires)"
