Pull xfs updates from Dave Chinner:
"The major addition is the new iomap based block mapping
infrastructure. We've been kicking this about locally for years, but
there are other filesystems want to use it too (e.g. gfs2). Now it
is fully working, reviewed and ready for merge and be used by other
filesystems.
There are a lot of other fixes and cleanups in the tree, but those are
XFS internal things and none are of the scale or visibility of the
iomap changes. See below for details.
I am likely to send another pull request next week - we're just about
ready to merge some new functionality (on disk block->owner reverse
mapping infrastructure), but that's a huge chunk of code (74 files
changed, 7283 insertions(+), 1114 deletions(-)) so I'm keeping that
separate to all the "normal" pull request changes so they don't get
lost in the noise.
Summary of changes in this update:
- generic iomap based IO path infrastructure
- generic iomap based fiemap implementation
- xfs iomap based Io path implementation
- buffer error handling fixes
- tracking of in flight buffer IO for unmount serialisation
- direct IO and DAX io path separation and simplification

Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
the legacy port io space that was designated for ipmi. Architectures
that do not map legacy port io can panic when trydefaults=1.
Rather than implement build-time conditional exceptions for each
architecture that does not map legacy port io, we have removed legacy
port io from the driver.
Parameter 'trydefaults' has been removed. Attempts to use it hereafter
will evoke the "Unknown symbol in module, or unknown parameter" message.
The patch was built against a number of architectures and tested for
regressions and functionality on x86_64 and ARM64.

The SIMPLE_DEV_PM_OPS macro deals with the CONFIG_PM options when

Suppose that stop_machine(fn) hangs because fn() hangs. In this case NMI
hard-lockup can be triggered on another CPU which does nothing wrong and
the trace from nmi_panic() won't help to investigate the problem.
And this change "fixes" the problem we (seem to) hit in practice.
- stop_two_cpus(0, 1) races with show_state_filter() running on CPU_0.
- CPU_1 already spins in MULTI_STOP_PREPARE state, it detects the soft
lockup and tries to report the problem.
- show_state_filter() enables preemption, CPU_0 calls multi_cpu_stop()
which goes to MULTI_STOP_DISABLE_IRQ state and disables interrupts.
- CPU_1 spends more than 10 seconds trying to flush the log buffer to
the slow serial console.

Setting TS_COMPAT in ptrace is wrong: if we happen to do it during
syscall entry, then we'll confuse seccomp and audit. (The former
isn't a security problem: seccomp is currently entirely insecure if a
malicious ptracer is attached.) As a minimal fix, this patch adds a
new flag TS_I386_REGS_POKED that handles the ptrace special case.

bool aa_g_hash_policy = CONFIG_SECURITY_APPARMOR_HASH_DEFAULT;
The problem is that the macro undefined in this case, and we need to use the IS_ENABLED()

Another minor problem with the original patch is that the option is even offered
in sysfs when SECURITY_APPARMOR_HASH is not enabled, so this also hides the option

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.
No functional changes were introduced.

Update the hvc driver to use the OPAL irqchip if made available by the

Commit 2def86a720 ("hvc: Convert to using interrupts instead of opal
events") enabled the use of interrupts in the hvc_driver for OPAL
platforms. However on machines with more than one hvc console, any
console after the first will fail to register an interrupt handler in
notifier_add_irq() since all consoles share the same IRQ number but do
not set the IRQF_SHARED flag:
genirq: Flags mismatch irq 31. 00000000 (hvc_console) vs. 00000000 (hvc_console)
hvc_open: request_irq failed with rc -16.
This error propagates up to hvc_open() and the console is closed, but
OPAL will still generate interrupts that are not handled, leading to
rcu_sched stall warnings.
Set IRQF_SHARED when calling request_irq(), allowing additional consoles
to start properly. This is only set for consoles handled by
hvc_opal_probe(), leaving other types unaffected.

regmap: irq: Add support to call client specific pre/post interrupt service
regmap: Add file patterns for regmap device tree bindings
Core changes:
- The big item is of course the completion of the character
device ABI. It has now replaced and surpassed the former
unmaintainable sysfs ABI: we can now hammer (bitbang)
individual lines or sets of lines and read individual lines
or sets of lines from userspace, and we can also register
to listen to GPIO events from userspace. As a tie-in we
have two new tools in tools/gpio: gpio-hammer and
gpio-event-mon that illustrate the proper use of the new
ABI. As someone said: the wild west days of GPIO are now
over.
- Continued to remove the pointless
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols.
I'm patching hexagon, openrisc, powerpc, sh, unicore,
ia64 and microblaze. These are either ACKed by their
maintainers or patched anyways after a grace period and
no response from maintainers. Some archs (ARM) come in from
their trees, and others (x86) are still not fixed, so I
might send a second pull request to root it out later in
this merge window, or just defer to v4.9.
- The GPIO tools are moved to the tools build system.
New drivers:
- New driver for the MAX77620/MAX20024.
- New driver for the Intel Merrifield.
- Enabled PCA953x for the TI PCA9536.
- Enabled PCA953x for the Intel Edison.
- Enabled R8A7792 in the RCAR driver.
Driver improvements:
- The STMPE and F7188x now supports the .get_direction()
callback.
- The Xilinx driver supports setting multiple lines at
once.
- ACPI support for the Vulcan GPIO controller.
- The MMIO GPIO driver supports device tree probing.
- The Acer One 10 is supported through the _DEP ACPI
attribute.
Cleanups:
- A major cleanup of the OF/DT support code. It is way
easier to read and understand now, probably this improves
performance too.
- Drop a few redundant .owner assignments.
- Remove CLPS711x boardfile support: we are 100% DT.

Merge tag 'gpio-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.8 kernel cycle. The big
news is the completion of the chardev ABI which I'm very happy about
and apart from that it's an ordinary, quite busy cycle. The details
are below.
The patches are tested in linux-next for some time, patches to other
subsystem mostly have ACKs.
I got overly ambitious with configureing lines as input for IRQ lines
but it turns out that some controllers have their interrupt-enable and
input-enabling in orthogonal settings so the assumption that all IRQ
lines are input lines does not hold. Oh well, revert and back to the
drawing board with that.
Core changes:
- The big item is of course the completion of the character device
ABI. It has now replaced and surpassed the former unmaintainable
sysfs ABI: we can now hammer (bitbang) individual lines or sets of
lines and read individual lines or sets of lines from userspace,
and we can also register to listen to GPIO events from userspace.
As a tie-in we have two new tools in tools/gpio: gpio-hammer and
gpio-event-mon that illustrate the proper use of the new ABI. As
someone said: the wild west days of GPIO are now over.
- Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
Kconfig symbols. I'm patching hexagon, openrisc, powerpc, sh,
unicore, ia64 and microblaze. These are either ACKed by their
maintainers or patched anyways after a grace period and no response
from maintainers.
Some archs (ARM) come in from their trees, and others (x86) are
still not fixed, so I might send a second pull request to root it
out later in this merge window, or just defer to v4.9.
- The GPIO tools are moved to the tools build system.
New drivers:
- New driver for the MAX77620/MAX20024.
- New driver for the Intel Merrifield.
- Enabled PCA953x for the TI PCA9536.
- Enabled PCA953x for the Intel Edison.
- Enabled R8A7792 in the RCAR driver.
Driver improvements:
- The STMPE and F7188x now supports the .get_direction() callback.
- The Xilinx driver supports setting multiple lines at once.
- ACPI support for the Vulcan GPIO controller.
- The MMIO GPIO driver supports device tree probing.
- The Acer One 10 is supported through the _DEP ACPI attribute.
Cleanups:
- A major cleanup of the OF/DT support code. It is way easier to
read and understand now, probably this improves performance too.
- Drop a few redundant .owner assignments.
- Remove CLPS711x boardfile support: we are 100% DT"

Cleanups:
- remove some unused defines, and also some obfuscatory ones.
- remove a redundant xattr handler.
- Remove useless xattr prefix arguments.
- Be more picky about uid and gid handling WRT namespaces.
Our use of current_user_ns() instead of init_user_ns left
open the possibility that users could spoof their uids
or gids when the server was running in a different namespace
in "default security" mode.
- Allow open(2) to succeed with O_DIRECT.
