Use memblock_add_node to add new memblock region within a NUMA node
in early_parse_mem() under CONFIG_NUMA, otherwise the mem parameter
can not work well.

In the current code, the users usually need to make sure the value
of mem parameter is correct, but it is better to do some check to
avoid potential boot hangs.
This commit checks whether mem parameter is empty, if yes, return
-EINVAL before call memblock_remove() and memblock_add().

is set
When CONFIG_PPC_64S_HASH_MMU is not set, slice.c is not built and
arch_get_unmapped_area() and arch_get_unmapped_area_topdown() are
not provided because RADIX uses the generic ones.
Therefore, neither set HAVE_ARCH_UNMAPPED_AREA nor
HAVE_ARCH_UNMAPPED_AREA_TOPDOWN.

include/{linux,asm-generic}/export.h defines a weak symbol, __crc_*
as a placeholder.
Genksyms writes the version CRCs into the linker script, which will be
used for filling the __crc_* symbols. The linker script format depends
on CONFIG_MODULE_REL_CRCS. If it is enabled, __crc_* holds the offset
to the reference of CRC.
It is time to get rid of this complexity.
Now that modpost parses text files (.*.cmd) to collect all the CRCs,
it can generate C code that will be linked to the vmlinux or modules.
Generate a new C file, .vmlinux.export.c, which contains the CRCs of
symbols exported by vmlinux. It is compiled and linked to vmlinux in
scripts/link-vmlinux.sh.
Put the CRCs of symbols exported by modules into the existing *.mod.c
files. No additional build step is needed for modules. As before,
*.mod.c are compiled and linked to *.ko in scripts/Makefile.modfinal.
No linker magic is used here. The new C implementation works in the
same way, whether CONFIG_RELOCATABLE is enabled or not.
CONFIG_MODULE_REL_CRCS is no longer needed.
Previously, Kbuild invoked additional $(LD) to update the CRCs in
objects, but this step is unneeded too.

All three versions of klp_arch_set_pc() do exactly the same: they
call ftrace_instruction_pointer_set().
Call ftrace_instruction_pointer_set() directly and remove
klp_arch_set_pc().
As klp_arch_set_pc() was the only thing remaining in asm/livepatch.h
on x86 and s390, remove asm/livepatch.h
livepatch.h remains on powerpc but its content is exclusively used
by powerpc specific code.

Pull arm64 updates from Catalin Marinas:
- Initial support for the ARMv9 Scalable Matrix Extension (SME).
SME takes the approach used for vectors in SVE and extends this to
provide architectural support for matrix operations. No KVM support
yet, SME is disabled in guests.
- Support for crashkernel reservations above ZONE_DMA via the
'crashkernel=X,high' command line option.
- btrfs search_ioctl() fix for live-lock with sub-page faults.
- arm64 perf updates: support for the Hisilicon "CPA" PMU for
monitoring coherent I/O traffic, support for Arm's CMN-650 and
CMN-700 interconnect PMUs, minor driver fixes, kerneldoc cleanup.
- Kselftest updates for SME, BTI, MTE.
- Automatic generation of the system register macros from a 'sysreg'
file describing the register bitfields.
- Update the type of the function argument holding the ESR_ELx register
value to unsigned long to match the architecture register size
(originally 32-bit but extended since ARMv8.0).
- stacktrace cleanups.
- ftrace cleanups.
- Miscellaneous updates, most notably: arm64-specific huge_ptep_get(),
avoid executable mappings in kexec/hibernate code, drop TLB flushing
from get_clear_flush() (and rename it to get_clear_contig()),
ARCH_NR_GPIO bumped to 2048 for ARCH_APPLE.

Pull x86 SGX updates from Dave Hansen:
"A set of patches to prevent crashes in SGX enclaves under heavy memory
pressure:
SGX uses normal RAM allocated from special shmem files as backing
storage when it runs out of SGX memory (EPC). The code was overly
aggressive when freeing shmem pages and was inadvertently freeing
perfectly good data. This resulted in failures in the SGX instructions
used to swap data back into SGX memory.
This turned out to be really hard to trigger in mainline. It was
originally encountered testing the out-of-tree "SGX2" patches, but
later reproduced on mainline.
Fix the data loss by being more careful about truncating pages out of
the backing storage and more judiciously setting pages dirty"

Pull Intel TDX support from Borislav Petkov:
"Intel Trust Domain Extensions (TDX) support.
This is the Intel version of a confidential computing solution called
Trust Domain Extensions (TDX). This series adds support to run the
kernel as part of a TDX guest. It provides similar guest protections
to AMD's SEV-SNP like guest memory and register state encryption,
memory integrity protection and a lot more.
Design-wise, it differs from AMD's solution considerably: it uses a
software module which runs in a special CPU mode called (Secure
Arbitration Mode) SEAM. As the name suggests, this module serves as
sort of an arbiter which the confidential guest calls for services it
needs during its lifetime.
Just like AMD's SNP set, this series reworks and streamlines certain
parts of x86 arch code so that this feature can be properly
accomodated"

Pull AMD SEV-SNP support from Borislav Petkov:
"The third AMD confidential computing feature called Secure Nested
Paging.
Add to confidential guests the necessary memory integrity protection
against malicious hypervisor-based attacks like data replay, memory
remapping and others, thus achieving a stronger isolation from the
hypervisor.
At the core of the functionality is a new structure called a reverse
map table (RMP) with which the guest has a say in which pages get
assigned to it and gets notified when a page which it owns, gets
accessed/modified under the covers so that the guest can take an
appropriate action.
In addition, add support for the whole machinery needed to launch a
SNP guest, details of which is properly explained in each patch.
And last but not least, the series refactors and improves parts of the
previous SEV support so that the new code is accomodated properly and
not just bolted on"

Pull interrupt handling updates from Thomas Gleixner:
"Core code:
- Make the managed interrupts more robust by shutting them down in
the core code when the assigned affinity mask does not contain
online CPUs.
- Make the irq simulator chip work on RT

Drivers:
- A set of changes which mark GPIO interrupt chips immutable to
prevent the GPIO subsystem from modifying it under the hood. This
provides the necessary infrastructure and converts a set of GPIO

Merge PM core changes, updates related to system sleep and power capping
updates for 5.19-rc1:
- Export dev_pm_ops instead of suspend() and resume() in the IIO
chemical scd30 driver (Jonathan Cameron).
- Add namespace variants of EXPORT[_GPL]_SIMPLE_DEV_PM_OPS and
PM-runtime counterparts (Jonathan Cameron).
- Move symbol exports in the IIO chemical scd30 driver into the
IIO_SCD30 namespace (Jonathan Cameron).
- Avoid device PM-runtime usage count underflows (Rafael Wysocki).
- Allow dynamic debug to control printing of PM messages (David
Cohen).
- Fix some kernel-doc comments in hibernation code (Yang Li, Haowen
Bai).
- Preserve ACPI-table override during hibernation (Amadeusz Sławiński).
- Improve support for suspend-to-RAM for PSCI OSI mode (Ulf Hansson).
- Make Intel RAPL power capping driver support the RaptorLake and
AlderLake N processors (Zhang Rui, Sumeet Pawnikar).
- Remove redundant store to value after multiply in the RAPL power
capping driver (Colin Ian King).

The function arch_sync_dma_for_cpu_all() was used but was
missing a prototype declaration.

ASoC: Updates for v5.19
This is quite a big update, partly due to the addition of some larger
drivers (more of which is to follow since at least the AVS driver is
still a work in progress) and partly due to Charles' work sorting out
our handling of endianness. As has been the case recently it's much
more about drivers than the core.
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs.
- Initial stages of Intel AVS driver merge.
- Introduction of v4 IPC mechanism for SOF.
- TDM mode support for AK4613.
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
