19ec11a223 gpio: em: remove the gpiochip before removing the irq domain
In commit 8764c4ca50 ("gpio: em: use the managed version of
gpiochip_add_data()") we implicitly altered the ordering of resource
freeing: since gpiochip_remove() calls gpiochip_irqchip_remove()
internally, we now can potentially use the irq_domain after it was
destroyed in the remove() callback (as devm resources are freed after
remove() has returned).

Use devm_add_action_or_reset() to keep the ordering right and entirely
kill the remove() callback in the driver.

89fea04c85 gpiolib: of: fix a memory leak in of_gpio_flags_quirks()
Each iteration of for_each_child_of_node puts the previous node, but in
the case of a break from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the break.
Issue found with Coccinelle.

dfd6f9ad36 ACPI: fix false-positive -Wuninitialized warning
clang gets confused by an uninitialized variable in what looks
to it like a never executed code path:

arch/x86/kernel/acpi/boot.c:618:13: error: variable 'polarity' is uninitialized when used here [-Werror,-Wuninitialized]
        polarity = polarity ? ACPI_ACTIVE_LOW : ACPI_ACTIVE_HIGH;
                   ^~~~~~~~
arch/x86/kernel/acpi/boot.c:606:32: note: initialize the variable 'polarity' to silence this warning
        int rc, irq, trigger, polarity;
                                      ^
                                       = 0
arch/x86/kernel/acpi/boot.c:617:12: error: variable 'trigger' is uninitialized when used here [-Werror,-Wuninitialized]
        trigger = trigger ? ACPI_LEVEL_SENSITIVE : ACPI_EDGE_SENSITIVE;
                  ^~~~~~~
arch/x86/kernel/acpi/boot.c:606:22: note: initialize the variable 'trigger' to silence this warning
        int rc, irq, trigger, polarity;
                            ^
                             = 0

This is unfortunately a design decision in clang and won't be fixed.

Changing the acpi_get_override_irq() macro to an inline function
reliably avoids the issue.

 "Improvements and bug fixes for the hmm interface in the kernel:

   - Improve clarity, locking and APIs related to the 'hmm mirror'

   - Remove old or transitional hmm APIs. These are hold overs from the
     past with no users, or APIs that existed only to manage cross tree
     conflicts. There are still a few more of these cleanups that didn't
     make the merge window cut off.

   - Improve some core mm APIs:
       - export alloc_pages_vma() for driver use
       - refactor into devm_request_free_mem_region() to manage
         DEVICE_PRIVATE resource reservations
       - refactor duplicative driver code into the core dev_pagemap

   - Remove hmm wrappers of improved core mm APIs, instead have drivers

Pull stream_open() updates from Kirill Smelkov:
 "This time on stream_open front it is only two small changes:

     wait_event_.* functions that were considered as blocking, but this
     was falsely reporting several deadlock cases as only warning.

     This was picked by linux-kbuild and entered mainline as commit
     0c4ab18fc3 ("coccinelle: api/stream_open: treat all wait_.*()
     calls as blocking"), and already merged earlier.

   - the second one teaches stream_open.cocci to consider files as being
     stream-like even if they use noop_llseek. It results in two more
     drivers being converted to stream_open() (mousedev.c and
     hid-sensor-custom.c)"

Pull x86 platform driver updates from Andy Shevchenko:
 "Gathered a bunch of x86 platform driver changes. It's rather big,
  since includes two big refactors and completely new driver:

   - ASUS WMI driver got a big refactoring in order to support the TUF
     Gaming laptops. Besides that, the regression with backlight being
     permanently off on various EeePC laptops has been fixed.

   - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
     X axis being inverted. This has been fixed.

   - Intel PMC core driver has been extended to be ACPI enumerated if
     the DSDT provides device with _HID "INT33A1". This allows to
     convert the driver to be pure platform and support new hardware
     purely based on ACPI DSDT.

   - From now on the Intel Speed Select Technology is supported thru a
     corresponding driver. This driver provides an access to the
     features of the ISST, such as Performance Profile, Core Power, Base
     frequency and Turbo Frequency.

   - Mellanox platform drivers has been refactored and now extended to
     support more systems, including new coming ones.

   - The OLPC XO-1.75 platform is now supported.

   - CB4063 Beckhoff Automation board is using PMC clocks, provided via
     pmc_atom driver, for ethernet controllers in a way that they can't
     be managed by the clock driver. The quirk has been extended to
     cover this case.

   - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
     the information of Chuwi Hi10 Air has been fixed to cover more
     models based on the same platform.

   - Xiaomi notebooks have WMI interface enabled. Thus, the driver to
     support it has been provided. It required some extension of the
     generic WMI library, which allows to propagate opaque context to
     the ->probe() of the individual drivers.

  This release includes debugfs clean up from Greg KH for several
  drivers that drop return code check and make debugfs absence or
  failure non-fatal.

  Also miscellaneous fixes here and there, mostly for Acer WMI and
  various Intel drivers"

05a70a8ec2 unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3
This lets us catch new architectures that implicitly make use of clone3
without setting __ARCH_WANT_SYS_CLONE3.
Failing on missing __ARCH_WANT_SYS_CLONE3 is a good indicator that they
either did not really want this syscall or haven't really thought about
whether it needs special treatment and just accidently included it in
their entrypoints by e.g. generating their syscall table automatically
via asm-generic/unistd.h

This patch has been compile-tested for the h8300 architecture which is
one of the architectures that does not yet implement clone3 and
generates its syscall table via asm-generic/unistd.h.

1a271a68e0 arch: mark syscall number 435 reserved for clone3
A while ago Arnd made it possible to give new system calls the same
syscall number on all architectures (except alpha). To not break this
nice new feature let's mark 435 for clone3 as reserved on all
architectures that do not yet implement it.
Even if an architecture does not plan to implement it this ensures that
new system calls coming after clone3 will have the same number on all
architectures.

028b6e8a89 clone: fix CLONE_PIDFD support
The introduction of clone3 syscall accidentally broke CLONE_PIDFD
support in traditional clone syscall on compat x86 and those
architectures that use do_fork to implement clone syscall.

This bug was found by strace test suite.

3975b097e5 *: convert stream-like files -> stream_open, even if they use noop_llseek
This patch continues 10dce8af34 (fs: stream_open - opener for
stream-like files so that read and write can run simultaneously without
deadlock) and c5bf68fe0c (*: convert stream-like files from
nonseekable_open -> stream_open) and teaches steam_open.cocci to
consider files as being stream-like not only if they have
.llseek=no_llseek, but also if they have .llseek=noop_llseek.

This is safe to do: the comment about noop_llseek says

	This is an implementation of ->llseek useable for the rare special case when
	userspace expects the seek to succeed but the (device) file is actually not
	able to perform the seek. In this case you use noop_llseek() instead of
	falling back to the default implementation of ->llseek.

and in general noop_llseek was massively added to drivers in 6038f373a3
(llseek: automatically add .llseek fop) when changing default for NULL .llseek
from NOP to no_llseek with the idea to avoid breaking compatibility, if
maybe some user-space program was using lseek on a device without caring
about the result, but caring if it was an error or not.

Amended semantic patch produces two changes when applied tree-wide:

        drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open.
        drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

 "Notable changes:

   - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver,

   - A fix for a bug in our handling of hardware watchpoints (eg. perf

     kernel crashes.

   - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for
     vmalloc when using the Radix MMU.

   - A large but incremental rewrite of our exception handling code to
     use gas macros rather than multiple levels of nested CPP macros.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.3 kernel cycle:

  Core changes:

   - Device links can optionally be added between a pin control producer
     and its consumers. This will affect how the system power management
     is handled: a pin controller will not suspend before all of its
     consumers have been suspended.

     This was necessary for the ST Microelectronics STMFX expander and
     need to be tested on other systems as well: it makes sense to make
     this default in the long run.

     Right now it is opt-in per driver.

   - Drive strength can be specified in microamps. With decreases in
     silicon technology, milliamps isn't granular enough, let's make it
     possible to select drive strengths in microamps.

     Right now the Meson (AMlogic) driver needs this.

  New drivers:

   - New subdriver for the Tegra 194 SoC.

   - New subdriver for the Qualcomm SDM845.

   - New subdriver for the Qualcomm SM8150.

   - New subdriver for the Freescale i.MX8MN (Freescale is now a product
     line of NXP).

   - New subdriver for Marvell MV98DX1135.

  Driver improvements:

   - The Bitmain BM1880 driver now supports pin config in addition to
     muxing.

   - The Qualcomm drivers can now reserve some GPIOs as taken aside and
     not usable for users. This is used in ACPI systems to take out some
     GPIO lines used by the BIOS so that noone else (neither kernel nor
     userspace) will play with them by mistake and crash the machine.

   - A slew of refurbishing around the Aspeed drivers (board management
     controllers for servers) in preparation for the new Aspeed AST2600
     SoC.

   - A slew of improvements over the SH PFC drivers as usual.

   - Misc cleanups and fixes"

If REGMAP_SPI is m and RTC_DRV_PCF2123 is y,

drivers/rtc/rtc-pcf2123.o: In function `pcf2123_probe':
rtc-pcf2123.c:(.text+0xb2b): undefined reference to `__devm_regmap_init_spi'

Select REGMAP_SPI as RTC_DRV_DS1347 driver does.

a2d79c7174 Merge tag 'for-5.3/io_uring-20190711' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:
 "This contains:

   - Support for recvmsg/sendmsg as first class opcodes.

     I don't envision going much further down this path, as there are
     plans in progress to support potentially any system call in an
     async fashion through io_uring. But I think it does make sense to
     have certain core ops available directly, especially those that can
     support a "try this non-blocking" flag/mode. (me)

   - Handle generic short reads automatically.

     This can happen fairly easily if parts of the buffered read is
     cached. Since the application needs to issue another request for
     the remainder, just do this internally and save kernel/user
     roundtrip while providing a nicer more robust API. (me)

   - Support for linked SQEs.

     This allows SQEs to depend on each other, enabling an application
     to eg queue a read-from-this-file,write-to-that-file pair. (me)

   - Fix race in stopping SQ thread (Jackie)"

5b596830d9 nfs4.0: Refetch lease_time after clientid update
RFC 7530 requires us to refetch the lease time attribute once a new
clientID is established. This is already implemented for the
nfs4.1(+) clients by nfs41_init_clientid, which calls
nfs41_finish_session_reset, which calls nfs4_setup_state_renewal.

To make nfs4_setup_state_renewal available for nfs4.0, move it
further to the top of the source file to include it regardles of
CONFIG_NFS_V4_1 and to save a forward declaration.

Call nfs4_setup_state_renewal from nfs4_init_clientid.

ea51efaa96 nfs4: Rename nfs41_setup_state_renewal
The function nfs41_setup_state_renewal is useful to the nfs 4.0 client
as well, so rename the function to nfs4_setup_state_renewal.
