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.

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

- 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
struct

- the first one converts stream_open.cocci to treat all functions that
start with wait_.* as blocking. Previously it was only wait_event_.*
functions that were considered as blocking, but this was falsely
reporting several deadlock cases as only warning. The patch was
picked by linux-kbuild and entered mainline as 0c4ab18fc3.
It is thus omitted from hereby pull-request.
- the second one teaches stream_open.cocci to consider files as being
stream-like even if they use noop_llseek. I posted this patch for
review 3 weeks ago[1], but got neither feedback nor complaints.

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.
Miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers.
The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle:

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.
