CONFIG_COMPAT_VDSO is defined by passing '-DCONFIG_COMPAT_VDSO' to the
compiler when the generic compat vDSO code is in use. It's much cleaner
and simpler to expose this as a proper Kconfig option (like x86 does),
so do that and remove the bodge.

For consistency with CROSS_COMPILE_COMPAT, mechanically rename COMPATCC
to CC_COMPAT so that specifying aspects of the compat vDSO toolchain in
the environment isn't needlessly confusing.

Directly passing the '--target' option to clang by appending to
COMPATCC does not work if COMPATCC has been specified explicitly as
an argument to Make unless the 'override' directive is used, which is
ugly and different to what is done in the top-level Makefile.
Move the '--target' option for clang out of COMPATCC and into
VDSO_CAFLAGS, where it will be picked up when compiling and assembling
the 32-bit vDSO under clang.

KBUILD_CPPFLAGS is defined differently depending on whether the main
compiler is clang or not. This means that it is not possible to build
the compat vDSO with GCC if the rest of the kernel is built with clang.
Define VDSO_CPPFLAGS directly to break this dependency and allow a clang
kernel to build a compat vDSO with GCC:
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \
CROSS_COMPILE_COMPAT=arm-linux-gnueabihf- CC=clang \

The .config file and the generated include/config/auto.conf can
end up out of sync after a set of commands since
CONFIG_CROSS_COMPILE_COMPAT_VDSO is not updated correctly.
The sequence can be reproduced as follows:
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig
[...]
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
[set CONFIG_CROSS_COMPILE_COMPAT_VDSO="arm-linux-gnueabihf-"]
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
Which results in:
arch/arm64/Makefile:62: CROSS_COMPILE_COMPAT not defined or empty,
the compat vDSO will not be built
even though the compat vDSO has been built:
$ file arch/arm64/kernel/vdso32/vdso.so
arch/arm64/kernel/vdso32/vdso.so: ELF 32-bit LSB pie executable, ARM,
EABI5 version 1 (SYSV), dynamically linked,
BuildID[sha1]=c67f6c786f2d2d6f86c71f708595594aa25247f6, stripped
A similar case that involves changing the configuration parameter
multiple times can be reconducted to the same family of problems.
Remove the use of CONFIG_CROSS_COMPILE_COMPAT_VDSO altogether and
instead rely on the cross-compiler prefix coming from the environment
via CROSS_COMPILE_COMPAT, much like we do for the rest of the kernel.

When detecting a spurious EL1 translation fault, we attempt to compare
ESR_EL1.DFSC with PAR_EL1.FST. We erroneously use FIELD_PREP() to
extract PAR_EL1.FST, when we should be using FIELD_GET().
In the wise words of Robin Murphy:
| FIELD_GET() is a UBFX, FIELD_PREP() is a BFI
Using FIELD_PREP() means that that dfsc & ESR_ELx_FSC_TYPE is always
zero, and hence not equal to ESR_ELx_FSC_FAULT. Thus we detect any
unhandled translation fault as spurious.
... so let's use FIELD_GET() to ensure we don't decide all translation
faults are spurious. ESR_EL1.DFSC occupies bits [5:0], and requires no
shifting.

The RockPro64 schematic [1] page 18 states a min voltage of 0.8V and a
max voltage of 1.4V for the VDD_LOG pwm regulator. However, there is an
additional note that the pwm parameter needs to be modified.
From the schematics a voltage range of 0.8V to 1.7V can be calculated.
Additional voltage measurements on the board show that this fix indeed
leads to the correct voltage, while without this fix the voltage was set
too high.

CPUs affected by Neoverse-N1 #1542419 may execute a stale instruction if
it was recently modified. The affected sequence requires freshly written
instructions to be executable before a branch to them is updated.
There are very few places in the kernel that modify executable text,
all but one come with sufficient synchronisation:
* The module loader's flush_module_icache() calls flush_icache_range(),
which does a kick_all_cpus_sync()
* bpf_int_jit_compile() calls flush_icache_range().
* Kprobes calls aarch64_insn_patch_text(), which does its work in
stop_machine().
* static keys and ftrace both patch between nops and branches to
existing kernel code (not generated code).
The affected sequence is the interaction between ftrace and modules.
The module PLT is cleaned using __flush_icache_range() as the trampoline
shouldn't be executable until we update the branch to it.
Drop the double-underscore so that this path runs kick_all_cpus_sync()
too.

Commit bd82d4bd21 ("arm64: Fix incorrect irqflag restore for priority

PSTATE.I bit set. This tells the pPNMI masking logic that interrupts
are masked by the CPU, not by the PMR. This value is read back by
local_daif_save().
Commit bd82d4bd21 added this call to el0_svc, as el0_svc_handler
is called with interrupts masked. el0_svc_compat was missed, but should
be covered in the same way as both of these paths end up in
el0_svc_common(), which expects to unmask interrupts.

If we take an unhandled fault in the kernel, we call show_pte() to dump
the {PGDP,PGD,PUD,PMD,PTE} values for the corresponding page table walk,
where the PGDP value is virt_to_phys(mm->pgd).
The boot-time and runtime kernel page tables, init_pg_dir and
swapper_pg_dir respectively, are kernel symbols. Thus, it is not valid
to call virt_to_phys() on either of these, though we'll do so if we take
a fault on a TTBR1 address.
When CONFIG_DEBUG_VIRTUAL is not selected, virt_to_phys() will silently
fix this up. However, when CONFIG_DEBUG_VIRTUAL is selected, this
results in splats as below. Depending on when these occur, they can
happen to suppress information needed to debug the original unhandled
fault, such as the backtrace:

We can avoid this by ensuring that we call __pa_symbol() for

don't need to handle these specially.

The HWCAP framework will detect a new capability based on the sanitized
version of the ID registers.
Sanitization is based on a whitelist, so any field not described will end
up to be zeroed.
At the moment, ID_AA64ISAR1_EL1.FRINTTS is not described in
ftr_id_aa64isar1. This means the field will be zeroed and therefore the
userspace will not be able to see the HWCAP even if the hardware
supports the feature.
This can be fixed by describing the field in ftr_id_aa64isar1.

As of ac7c3e4ff4 ("compiler: enable CONFIG_OPTIMIZE_INLINING forcibly"),
inline functions are no longer annotated with '__always_inline', which
allows the compiler to decide whether inlining is really a good idea or
not. Although this is a great idea on paper, the reality is that AArch64
GCC prior to 9.1 has been shown to get confused when creating an
out-of-line copy of a function passing explicit 'register' variables
into an inline assembly block:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91111
It's not clear whether this is specific to arm64 or not but, for now,
ensure that all of our functions using 'register' variables are marked
as '__always_inline' so that the old behaviour is effectively preserved.
Hopefully other architectures are luckier with their compilers.

line PMIC_INT_L from the RK808, and there's a note which translates as:

Tested by setting an RTC wakealarm and checking /proc/interrupts counters.
Without this patch, neither the rockchip_gpio_irq counter for the RK808,
nor the RTC alarm counter increment when the alarm time is reached.
With this patch, both interrupt counters increment by 1 as expected.

code (x86 and arm), with the functions themselves living in drivers/xen
as they are not architecture dependent.
As the setup is exactly the same for arm and x86 move the setup to
drivers/xen, too. This at once removes the need to make the single
functions global visible.

The system which has SVE feature crashed because of
the memory pointed by task->thread.sve_state was destroyed
by someone.
That is because sve_state is freed while the forking the
child process. The child process has the pointer of sve_state
which is same as the parent's because the child's task_struct
is copied from the parent's one. If the copy_process()
fails as an error on somewhere, for example, copy_creds(),
then the sve_state is freed even if the parent is alive.
The flow is as follows.
copy_process
p = dup_task_struct
=> arch_dup_task_struct
*dst = *src; // copy the entire region.
:
retval = copy_creds
if (retval < 0)
goto bad_fork_free;
:
bad_fork_free:
...
delayed_free_task(p);
=> free_task
=> arch_release_task_struct
=> fpsimd_release_task
=> __sve_free
=> kfree(task->thread.sve_state);
// free the parent's sve_state
Move child's sve_state = NULL and clearing TIF_SVE flag
to arch_dup_task_struct() so that the child doesn't free the
parent's one.
There is no need to wait until copy_process() to clear TIF_SVE for
dst, because the thread flags for dst are initialized already by
copying the src task_struct.
This change simplifies the code, so get rid of comments that are no
longer needed.
As a note, arm64 used to have thread_info on the stack. So it
would not be possible to clear TIF_SVE until the stack is initialized.
From commit c02433dd6d ("arm64: split thread_info from task stack"),
the thread_info is part of the task, so it should be valid to modify
the flag from arch_dup_task_struct().

It turns out that sopine-baseboard needs same fix as pine64-plus
for ethernet PHY. Here too Realtek ethernet PHY chip needs additional
power on delay to properly initialize. Datasheet mentions that chip
needs 30 ms to be properly powered on and that it needs some more time
to be initialized.
Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.
Note that issue was found out and fix tested on pine64-lts, but it's
basically the same as sopine-baseboard, only layout and connectors
differ.

Pull kernel lockdown mode from James Morris:
"This is the latest iteration of the kernel lockdown patchset, from
Matthew Garrett, David Howells and others.
From the original description:
This patchset introduces an optional kernel lockdown feature,
intended to strengthen the boundary between UID 0 and the kernel.
When enabled, various pieces of kernel functionality are restricted.
Applications that rely on low-level access to either hardware or the
kernel may cease working as a result - therefore this should not be
enabled without appropriate evaluation beforehand.
The majority of mainstream distributions have been carrying variants
of this patchset for many years now, so there's value in providing a
doesn't meet every distribution requirement, but gets us much closer
to not requiring external patches.
There are two major changes since this was last proposed for mainline:
- Separating lockdown from EFI secure boot. Background discussion is
covered here: https://lwn.net/Articles/751061/
- Implementation as an LSM, with a default stackable lockdown LSM
module. This allows the lockdown feature to be policy-driven,
rather than encoding an implicit policy within the mechanism.
The new locked_down LSM hook is provided to allow LSMs to make a
policy decision around whether kernel functionality that would allow
tampering with or examining the runtime state of the kernel should be
permitted.
The included lockdown LSM provides an implementation with a simple
policy intended for general purpose use. This policy provides a coarse
level of granularity, controllable via the kernel command line:
lockdown={integrity|confidentiality}
Enable the kernel lockdown feature. If set to integrity, kernel features
that allow userland to modify the running kernel are disabled. If set to
confidentiality, kernel features that allow userland to extract
confidential information from the kernel are also disabled.
This may also be controlled via /sys/kernel/security/lockdown and
overriden by kernel configuration.
New or existing LSMs may implement finer-grained controls of the
lockdown features. Refer to the lockdown_reason documentation in
include/linux/security.h for details.
The lockdown feature has had signficant design feedback and review
across many subsystems. This code has been in linux-next for some
weeks, with a few fixes applied along the way.
Stephen Rothwell noted that commit 9d1f8be5cf ("bpf: Restrict bpf
when kernel lockdown is in confidentiality mode") is missing a
Signed-off-by from its author. Matthew responded that he is providing
this under category (c) of the DCO"

The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.

architectures to benefit from those functions. Note that this new config
depends on MMU being enabled, if selected without MMU support, a warning
will be thrown.

Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem
cache for page table allocations on several architectures that do not use
PAGE_SIZE tables for one or more levels of the page table hierarchy.
Most architectures do not implement these functions and use __weak default
NOP implementation of pgd_cache_init(). Since there is no such default
for pgtable_cache_init(), its empty stub is duplicated among most
architectures.
Rename the definitions of pgd_cache_init() to pgtable_cache_init() and
drop empty stubs of pgtable_cache_init().

Patch series "mm: remove quicklist page table caches".
A while ago Nicholas proposed to remove quicklist page table caches [1].
I've rebased his patch on the curren upstream and switched ia64 and sh to
use generic versions of PTE allocation.
[1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com
This patch (of 3):
Remove page table allocator "quicklists". These have been around for a
long time, but have not got much traction in the last decade and are only
used on ia64 and sh architectures.
The numbers in the initial commit look interesting but probably don't
apply anymore. If anybody wants to resurrect this it's in the git
history, but it's unhelpful to have this code and divergent allocator
behaviour for minor archs.
Also it might be better to instead make more general improvements to page
allocator if this is still so slow.

it into the kernel.
The Armada 3720 based Turris Mox open source router platform is a late
addition and it follows some preparatory work across multiple branches.
The OMAP2+ platform had some large-scale cleanup involving driver
changes and DT changes, here we finish it off, dropping a lot of the
now-unused platform data.
The TI K3 platform that got added for 5.3 gains a lot more support
for individual bits on the SoC, this part just came late for the
merge window.

Pull ARM SoC late updates from Arnd Bergmann:
"This is some material that we picked up into our tree late or that had
complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the
most interesting new additions:
- The new Aspeed AST2600 baseboard management controller is added,
this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
had some dependencies on other device drivers.
- After many years, support for the MMP2 based OLPC XO-1.75 finally
makes it into the kernel.

[ This pull request itself wasn't actually sent late at all by Arnd, but
I waited on the branches that it used to be pulled first, so it ends
up being merged much later than the other ARM SoC pull requests this

Pull core timer updates from Thomas Gleixner:
"Timers and timekeeping updates:
- A large overhaul of the posix CPU timer code which is a preparation
for moving the CPU timer expiry out into task work so it can be
properly accounted on the task/process.
An update to the bogus permission checks will come later during the
merge window as feedback was not complete before heading of for
travel.
- Switch the timerqueue code to use cached rbtrees and get rid of the
homebrewn caching of the leftmost node.
- Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
single function
- Implement the separation of hrtimers to be forced to expire in hard
interrupt context even when PREEMPT_RT is enabled and mark the
affected timers accordingly.
- Implement a mechanism for hrtimers and the timer wheel to protect
RT against priority inversion and live lock issues when a (hr)timer
which should be canceled is currently executing the callback.
Instead of infinitely spinning, the task which tries to cancel the
timer blocks on a per cpu base expiry lock which is held and
released by the (hr)timer expiry code.
- Enable the Hyper-V TSC page based sched_clock for Hyper-V guests
resulting in faster access to timekeeping functions.
- Updates to various clocksource/clockevent drivers and their device
tree bindings.
- The usual small improvements all over the place"

Define a weak function in COND_SYSCALL instead of a weak alias to

On arm64 build with clang, sometimes the __cmpxchg_mb is not inlined
when CONFIG_OPTIMIZE_INLINING is set.
Clang then fails a compile-time assertion, because it cannot tell at
compile time what the size of the argument is:
mm/memcontrol.o: In function `__cmpxchg_mb':
memcontrol.c:(.text+0x1a4c): undefined reference to `__compiletime_assert_175'
memcontrol.c:(.text+0x1a4c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `__compiletime_assert_175'
Mark all of the cmpxchg() style functions as __always_inline to
ensure that the compiler can see the result.

This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit respectively.
There are lots of cleanups and additional hardware support for platforms
we already support based on SoCs from Renesas, ST-Microelectronics,
Intel/Altera, Rockchips, Allwinner, Broadcom and other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone platform,
usually paired with an external 5G modem. So far we only support the
Qualcomm SM8150 MTP reference platform, but no actual products.
For the slightly older Qualcomm platforms, support for several interesting
products is getting added: Three laptops based on Snapdragon 835/MSM8998
(Asus NovaGo, HP Envy X2 and Lenovo Miix 630), one laptop based on
Snapdragon 850/sdm850 (Lenovo Yoga C630) and several phones based on
the older Snapdragon 410/MSM8916 (Samsung A3 and A5, Longcheer L8150
aka Android One 2nd gen "seed" aka Wileyfox Swift).
Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
Allwinner V3 is a repackaged version of the existing low-end V3s chip,
and is used in the tiny Lichee Pi Zero plus, also added here. There is
also a new TV set-top box based on Allwinner H6, the Tanix TX6, and the
eMMC variant of the Olimex A64-Olinuxino development board.
NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC family,
similar to the i.MX8M Mini. As usual, there is a large number of new
boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML, SolidRun Hummingboard
Pulse baseboard and System-on-Module, Boundary Devices i.MX8MQ Nitrogen8M,
and TechNexion PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit,
we get the Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from their
set-top-box line and smart speaker with newer CPU and GPU cores compared
to their predecessors. Both are now also supported by the Khadas VIM3
development board series, and the dts files for that get reorganized a
bit to better deal with all variants. Another board based on SM1 that
gets added is the SEI Robotics SEI610.
There are a handful of new x86 and Power9 server boards using Aspeed BMC
chips that are gaining support for running Linux on the BMC through the
OpenBMC project: Facebook Minipack/Wedge100/Wedge40, Lenovo Hr855xg2,
and Mihawk. Notably these are still new machines using SoCs based on
the ARM9 and ARM11 CPU cores, as support for the new Cortex-A7 based
AST2600 is still ramping up.
There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the low-end
RK3229 chip, while the two AOpen products Chromebox Mini (Fievel) and
Chromebase Mini (Tiger) run ChromeOS and are meant for commercial settings
(digital signage, PoS, ...).
One more single-board computer based on the popular 64-bit RK3399 is
added: the Leez RK3399 P710.

The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody is
using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still in
active use and are converted to the ARCH_MULTIPLATFORM build, meaning
that we can compile a kernel that works on these along with most other
ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
but additional work is needed to complete this. Patches for the
remaining ARMv5 platforms have started but need more work and some
testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.

"Although there isn't tonnes of code in terms of line count, there are
a fair few headline features which I've noted both in the tag and also
in the merge commits when I pulled everything together.
The part I'm most pleased with is that we had 35 contributors this
time around, which feels like a big jump from the usual small group of
core arm64 arch developers. Hopefully they all enjoyed it so much that
they'll continue to contribute, but we'll see.
It's probably worth highlighting that we've pulled in a branch from
the risc-v folks which moves our CPU topology code out to where it can
be shared with others.

While parts of the VGIC support a large number of vcpus (we
bravely allow up to 512), other parts are more limited.
One of these limits is visible in the KVM_IRQ_LINE ioctl, which
only allows 256 vcpus to be signalled when using the CPU or PPI
types. Unfortunately, we've cornered ourselves badly by allocating
all the bits in the irq field.
Since the irq_type subfield (8 bit wide) is currently only taking
the values 0, 1 and 2 (and we have been careful not to allow anything
else), let's reduce this field to only 4 bits, and allocate the
remaining 4 bits to a vcpu2_index, which acts as a multiplier:
vcpu_id = 256 * vcpu2_index + vcpu_index
With that, and a new capability (KVM_CAP_ARM_IRQ_LINE_LAYOUT_2)
allowing this to be discovered, it becomes possible to inject
PPIs to up to 4096 vcpus. But please just don't.
Whilst we're there, add a clarification about the use of KVM_IRQ_LINE
on arm, which is not completely conditionned by KVM_CAP_IRQCHIP.

Update the AES-XTS implementation based on NEON instructions so that it
can deal with inputs whose size is not a multiple of the cipher block
size. This is part of the original XTS specification, but was never
implemented before in the Linux kernel.
Since the bit slicing driver is only faster if it can operate on at
least 7 blocks of input at the same time, let's reuse the alternate
path we are adding for CTS to process any data tail whose size is
not a multiple of 128 bytes.

Add the missing support for ciphertext stealing in the implementation
of AES-XTS, which is part of the XTS specification but was omitted up
until now due to lack of a need for it.
The asm helpers are updated so they can deal with any input size, as
long as the last full block and the final partial block are presented
at the same time. The glue code is updated so that the common case of
operating on a sector or page is mostly as before. When CTS is needed,
the walk is split up into two pieces, unless the entire input is covered
by a single step.

The pure NEON AES implementation predates the bit-slicing one, and is
generally slower, unless the algorithm in question can only execute
sequentially.
So advertising the skciphers that the bit-slicing driver implements as
well serves no real purpose, and we can just disable them. Note that the
bit-slicing driver also has a link time dependency on the pure NEON
driver, for CBC encryption and for XTS tweak calculation, so we still
need both drivers on systems that do not implement the Crypto Extensions.
At the same time, expose those modaliases for the AES instruction based
driver. This is necessary since otherwise, we may end up loading the
wrong driver when any of the skciphers are instantiated before the CPU
capability based module loading has completed.
Finally, add the missing modalias for cts(cbc(aes)) so requests for
this algorithm will autoload the correct module.

Daniel Borkmann says:
====================
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add the ability to use unaligned chunks in the AF_XDP umem. By
relaxing where the chunks can be placed, it allows to use an
arbitrary buffer size and place whenever there is a free
address in the umem. Helps more seamless DPDK AF_XDP driver
integration. Support for i40e, ixgbe and mlx5e, from Kevin and
Maxim.
2) Addition of a wakeup flag for AF_XDP tx and fill rings so the
application can wake up the kernel for rx/tx processing which
avoids busy-spinning of the latter, useful when app and driver
is located on the same core. Support for i40e, ixgbe and mlx5e,
from Magnus and Maxim.
3) bpftool fixes for printf()-like functions so compiler can actually
enforce checks, bpftool build system improvements for custom output
directories, and addition of 'bpftool map freeze' command, from Quentin.
4) Support attaching/detaching XDP programs from 'bpftool net' command,
from Daniel.
5) Automatic xskmap cleanup when AF_XDP socket is released, and several
barrier/{read,write}_once fixes in AF_XDP code, from Björn.
6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf
inclusion as well as libbpf versioning improvements, from Andrii.
7) Several new BPF kselftests for verifier precision tracking, from Alexei.
8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya.
9) And more BPF kselftest improvements all over the place, from Stanislav.
10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub.

Most of the basic infrastructure is completed for BM1880 SoC except
common clock support. We are still couple of patchset away from
booting a distro from eMMC/SD with mainline. Below are the changes
for this cycle:
- Added Reset controller support to BM1880 SoC based on reset-simple
driver.
- Modified pinctrl memory map for BM1880 SoC. The initial pinctrl support
included the PWM registers as a part of the pinctrl memory map. But this
turned out to be useless as PWM registers are not handling any pin muxing

Bitmain SoC changes for v5.4:
Most of the basic infrastructure is completed for BM1880 SoC except
common clock support. We are still couple of patchset away from
booting a distro from eMMC/SD with mainline. Below are the changes
for this cycle:
- Added Reset controller support to BM1880 SoC based on reset-simple
driver.
- Modified pinctrl memory map for BM1880 SoC. The initial pinctrl support
included the PWM registers as a part of the pinctrl memory map. But this
turned out to be useless as PWM registers are not handling any pin muxing
at all. So removed the PWM registers from pinctrl memory map.
