Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().
The callers are updated with the below semantic patch:
@@
expression addr;
expression size;
@@
- memblock_free(addr, size);
+ memblock_phys_free(addr, size);

Percpu embedded first chunk allocator is the firstly option, but it
could fails on ARM64, eg,
percpu: max_distance=0x5fcfdc640000 too large for vmalloc space 0x781fefff0000
percpu: max_distance=0x600000540000 too large for vmalloc space 0x7dffb7ff0000
percpu: max_distance=0x5fff9adb0000 too large for vmalloc space 0x5dffb7ff0000
then we could get
WARNING: CPU: 15 PID: 461 at vmalloc.c:3087 pcpu_get_vm_areas+0x488/0x838
and the system could not boot successfully.
Let's implement page mapping percpu first chunk allocator as a fallback
to the embedding allocator to increase the robustness of the system.

Pull ARM SoC driver updates from Arnd Bergmann:
"These are all the driver updates for SoC specific drivers. There are a
couple of subsystems with individual maintainers picking up their
patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this tree this
time. There are only minor changes, but they depend on other tegra
driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process. This
depends on a small sound driver change that is included here as
well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
layerscape, allwinner, broadcom, and omap"

Pull ARM SoC DT updates from Arnd Bergmann:
"This is a rather large update for the ARM devicetree files, after a
few quieter releases, with 775 total commits and 47 branches pulled
into this one.
There are 5 new SoC types plus some minor variations, and a total of
60 new machines, so I'm limiting the summary to the main noteworthy
items:
- Apple M1 gain support for PCI and pinctrl, getting a bit closer to
a usable system out of the box.
- Qualcomm gains support for Snapdragon 690 (aka SM6350) as well as
SM7225, 11 new smartphones, and three additional Chromebooks, and
improvements all over the place.
- Samsung gains support for ExynosAutov9, an automotive version of
their smartphone SoC, but otherwise no major changes.
- Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a number
of improvements for the recently added SAMA7 family. The LAN966 SoC
that was added in the platform code does not have dts files yet.
Two board files are added for the older at91sam9g20 SoC
- Aspeed supports two additional server boards using their AST2600 as
BMC, and improves support for qemu models

boards using RK3328/RK3399/RK3566, and one Chromebook tablet.
- Two NAS boxes are added using the ARMv4 based Gemini platform
- One new board is added to the Intel Arria SoC FPGA family
- Marvell adds one network switch based on Armada 381 and the new
MOCHAbin 7040 development board
- NXP adds support for the S32G2 automotive SoC, two imx6 based ebook
readers, and three additional development boards, which is notably
less than their usual additions, but they also gain improvements to
their many existing boards
- STmicroelectronics adds their stm32mp13 SoC family along with a
reference board
- Renesas adds new versions of their R-Car Gen3 SoCs and many updates
for their older generations
- Broadcom adds support for a number of Cisco Meraki wireless
controllers, along with two new boards and other updates for
BCM53xx/BCM47xx networking SoCs and the Raspberry Pi boards
- Mediatek improves support for the MT81xx SoCs used in Chromebooks
as well as the MT76xx networking SoCs
- NVIDIA adds a number of cleanups and additional support for more
hardware on the already supported machines
- TI K3 adds support for three new boards along with cleanups
- Toshiba adds one board for the Visconti family
- Xilinx adds five new ZynqMP based machines
- Amlogic support is added for the Radxa Zero and two Jethub home
automation controllers, along with changes to other machines
- Rob Herring continues his work on fixing dtc warnings all over the
tree.

Pull tracing updates from Steven Rostedt:
- kprobes: Restructured stack unwinder to show properly on x86 when a
stack dump happens from a kretprobe callback.
- Fix to bootconfig parsing
- Have tracefs allow owner and group permissions by default (only
denying others). There's been pressure to allow non root to tracefs
in a controlled fashion, and using groups is probably the safest.
- Bootconfig memory managament updates.
- Bootconfig clean up to have the tools directory be less dependent on
changes in the kernel tree.
- Allow perf to be traced by function tracer.
- Rewrite of function graph tracer to be a callback from the function
tracer instead of having its own trampoline (this change will happen
on an arch by arch basis, and currently only x86_64 implements it).
- Allow multiple direct trampolines (bpf hooks to functions) be batched
together in one synchronization.
- Allow histogram triggers to add variables that can perform
calculations against the event's fields.
- Use the linker to determine architecture callbacks from the ftrace
trampoline to allow for proper parameter prototypes and prevent
warnings from the compiler.
- Extend histogram triggers to key off of variables.
- Have trace recursion use bit magic to determine preempt context over
if branches.
- Have trace recursion disable preemption as all use cases do anyway.
- Added testing for verification of tracing utilities.
- Various small clean ups and fixes.

Pull thread_info update to move 'cpu' back from task_struct from Kees Cook:
"Cross-architecture update to move task_struct::cpu back into
thread_info on arm64, x86, s390, powerpc, and riscv. All Acked by arch
maintainers.
Quoting Ard Biesheuvel:
'Move task_struct::cpu back into thread_info
Keeping CPU in task_struct is problematic for architectures that
define raw_smp_processor_id() in terms of this field, as it
requires linux/sched.h to be included, which causes a lot of pain
in terms of circular dependencies (aka 'header soup')
This series moves it back into thread_info (where it came from)
for all architectures that enable THREAD_INFO_IN_TASK, addressing
the header soup issue as well as some pointless differences in the
implementations of task_cpu() and set_task_cpu()'"

Pull arm64 updates from Will Deacon:
"There's the usual summary below, but the highlights are support for
the Armv8.6 timer extensions, KASAN support for asymmetric MTE, the
ability to kexec() with the MMU enabled and a second attempt at
switching to the generic pfn_valid() implementation.
Summary:
- Support for the Arm8.6 timer extensions, including a
self-synchronising view of the system registers to elide some
expensive ISB instructions.
- Exception table cleanup and rework so that the fixup handlers
appear correctly in backtraces.
- A handful of miscellaneous changes, the main one being selection of
CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK.
- More mm and pgtable cleanups.
- KASAN support for "asymmetric" MTE, where tag faults are reported
synchronously for loads (via an exception) and asynchronously for
stores (via a register).
- Support for leaving the MMU enabled during kexec relocation, which
significantly speeds up the operation.
- Minor improvements to our perf PMU drivers.
- Improvements to the compat vDSO build system, particularly when
building with LLVM=1.
- Preparatory work for handling some Coresight TRBE tracing errata.
- Cleanup and refactoring of the SVE code to pave the way for SME
support in future.
- Ensure SCS pages are unpoisoned immediately prior to freeing them
when KASAN is enabled for the vmalloc area.
- Try moving to the generic pfn_valid() implementation again now that
the DMA mapping issue from last time has been resolved.
- Numerous improvements and additions to our FPSIMD and SVE
selftests"

Pull scheduler updates from Thomas Gleixner:
- Revert the printk format based wchan() symbol resolution as it can
leak the raw value in case that the symbol is not resolvable.
- Make wchan() more robust and work with all kind of unwinders by
enforcing that the task stays blocked while unwinding is in progress.

- Improve asymmetric packing logic
- Extend scheduler statistics to RT and DL scheduling classes and add
statistics for bandwith burst to the SCHED_FAIR class.
- Properly account SCHED_IDLE entities
- Prevent a potential deadlock when initial priority is assigned to a
newly created kthread. A recent change to plug a race between cpuset
and __sched_setscheduler() introduced a new lock dependency which is
now triggered. Break the lock dependency chain by moving the priority
assignment to the thread function.

- Improve idle balancing in general and especially for NOHZ enabled
systems.

Pull locking updates from Thomas Gleixner:
- Move futex code into kernel/futex/ and split up the kitchen sink into
seperate files to make integration of sys_futex_waitv() simpler.
- Add a new sys_futex_waitv() syscall which allows to wait on multiple
futexes.
The main use case is emulating Windows' WaitForMultipleObjects which
allows Wine to improve the performance of Windows Games. Also native
Linux games can benefit from this interface as this is a common wait
pattern for this kind of applications.
- Add context to ww_mutex_trylock() to provide a path for i915 to
rework their eviction code step by step without making lockdep upset
until the final steps of rework are completed. It's also useful for
regulator and TTM to avoid dropping locks in the non contended path.
- Lockdep and might_sleep() cleanups and improvements
- A few improvements for the RT substitutions.

Coresight changes for v5.16
- A new option to make coresight cpu-debug capabilities available as early
as possible in the kernel boot process.
- Make trace sessions more enduring by coping with scenarios where events
are scheduled on CPUs that can't reach the selected sink.
- A set of improvement to make the TMC-ETR driver more efficient.
- Enhancements to the TRBE driver to correct several errata.
- An enhancement to make the AXI burts size configurable for TMC devices
that can't work with the default value.
- A fix in the CTI module to use the correct device when calling
pm_runtime_put()
- The addition of the Kryo-5xx device to the list of support ETMs.

: <quote>
: The handle_domain_{irq,nmi}() functions were oringally intended as a

With 6caa5812e2d1 ("KVM: arm64: Use generic KVM xfer to guest work
function") all arm64 exit paths are properly equipped to handle the
POSIX timers' task work.
Deferring timer callbacks to thread context, not only limits the amount
of time spent in hard interrupt context, but is a safer
implementation[1], and will allow PREEMPT_RT setups to use KVM[2].
So let's enable POSIX_CPU_TIMERS_TASK_WORK on arm64.

At the moment, all the Minis running Linux have the same MAC
address (00:10:18:00:00:00), which is a bit annoying.
Expose the PCI node corresponding to the Ethernet device, and
declare a 'local-mac-address' property. The bootloader will update
it (m1n1 already has the required feature). And if it doesn't, then
the default value is already present in the DT.
This relies on forcing the bus number for each port so that the
endpoints connected to them are correctly numbered (and keeps dtc
quiet).

Qualcomm ARM64 DTS additional patches for v5.16
The RPM and RPMh sleep stats are introduced on a number of platforms, to
aid the enablement of entering low power mode.
The MSM8916 support receives some polishing touches, followed by
introduction of the necessary pieces to use the DeviceTree on 32-bit
variants of the MSM8916 platform, in particular to boot the secondary
CPUs. Based on this support for the Samsung Galaxy S4 Mini Value Edition
is introduced.
The Asus Zenfone 2 Laser gained touchscreen, sensors and sdcard support.
MSM8996 got support for the its crypto hardware and the Xiaomi Mi 5
gained a description of its LCD panel.
The Trogdor device on SC7180 gained support for a second source eDP
brigde, while SC7280 gains PCIe support and the newly introduced
Herobrine device.
Both MSM8916 and SDM845 has their standalong SMEM node dropped, in favour
of the newly introduced support for specifying the compatible directly
on the reserved-memory node.
The SM7225 platform is introduced, as a derrivative of SM6350, initial
support for the PM6350 PMIC and based on this the Fairphone 4 is
introduced.
The RB3 and RB5 devices gains msm-id and board-id, to allow the two DTBs
to be baked into a single boot.img that can be booted on both devices.
As the GDSC driver has been extended to properly describe the
relationship between MMCX and MDSS_GDSC, the now deprecated mmcx
regulator is removed from SM8250.
SM8350 gained CPU topology, idle-states and fastrpc support. FastRPC was
also added for SM8150 and the SA8155p ADP got a couple of remoteprocs
enabled.
Additionally a number of DT validation issues was corrected across the
various platforms and devices.

Qualcomm ARM64 defconfig updates for v5.16
The major change here is the disabling of the firmware loades user space
fallback, this is done as arm64 is the only platform with this flag
enabled and as a result doesn't play nice with standard distributions.
It then enables the new limits driver, which controls the hardware based
thermal mitigation on a range of Qualcomm platforms. The prima/pronto
WiFi and Bluetooth drivers are enabled to ensure these features works
out of the box, now that the last details in the dts are landed.
The new driver for acquiring sleep stats is enabled to facilitate the
various efforts on getting these platforms into low power mode.
Lastly the base SC7280 drivers needed to simply boot this platform are
enabled.
