Pull integrity updates from Mimi Zohar:
"Aside from the one EVM cleanup patch, all the other changes are kexec
related.
On different architectures different keyrings are used to verify the
kexec'ed kernel image signature. Here are a number of preparatory
cleanup patches and the patches themselves for making the keyrings -
builtin_trusted_keyring, .machine, .secondary_trusted_keyring, and
.platform - consistent across the different architectures"

Pull ARM new SoC support from Arnd Bergmann:
"This adds initial support for two SoC families that have been under
review for a while. In both cases, the origonal idea was to have a
minimally functional version, but we ended up leaving out the clk
drivers that are still under review and will be merged through the
corresponding subsystem tree.
The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and
based on the 32-bit NPCM7xx family but is now getting added to
arch/arm64 as well.
Sunplus SP7021, also known as Plus1, is a general-purpose
System-in-Package design based on the 32-bit Cortex-A7 SoC on the main

Pull ARM SoC defconfig updates from Arnd Bergmann:
"This branch includes the usual updates to defconfig files, enabling
additional driver support for the supported platforms.
There is also a global refresh for all of them that reorders the lines
according to the 'savedefconfig' output, but without removing lines
that are no longer part of the refresh.
I went through the most common removed lines to also address them
while making sure to catch renamed options and add them back under the
new name.
The boardfile deprecation branch is based on top of this to avoid
conflicts against removing the unused boardfile configs from the
generic defconfig files"

Pull ARM DT updates from Arnd Bergmann:
"As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
added here in addition to the reference boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the Orange Pi
zero2 single-board computer and the X96 Mate set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers, DH
electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and
phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix
10 Software Virtual platform, both in the SoCFPGA platform.
- Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000
Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm SoC
families brought added machines: Acer Chromebook 514 (MT8192), Acer
Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines
including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips: PCB8309
(Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC
Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)"

Pull arm64 updates from Will Deacon:
"Highlights include a major rework of our kPTI page-table rewriting
code (which makes it both more maintainable and considerably faster in
the cases where it is required) as well as significant changes to our
early boot code to reduce the need for data cache maintenance and
greatly simplify the KASLR relocation dance.
Summary:
- Remove unused generic cpuidle support (replaced by PSCI version)
- Fix documentation describing the kernel virtual address space
- Handling of some new CPU errata in Arm implementations
- Rework of our exception table code in preparation for handling
machine checks (i.e. RAS errors) more gracefully
- Switch over to the generic implementation of ioremap()
- Fix lockdep tracking in NMI context
- Instrument our memory barrier macros for KCSAN
- Rework of the kPTI G->nG page-table repainting so that the MMU
remains enabled and the boot time is no longer slowed to a crawl
for systems which require the late remapping
- Enable support for direct swapping of 2MiB transparent huge-pages
on systems without MTE
- Fix handling of MTE tags with allocating new pages with HW KASAN
- Expose the SMIDR register to userspace via sysfs
- Continued rework of the stack unwinder, particularly improving the
behaviour under KASAN
- More repainting of our system register definitions to match the
architectural terminology
- Improvements to the layout of the vDSO objects
- Support for allocating additional bits of HWCAP2 and exposing
FEAT_EBF16 to userspace on CPUs that support it
- Considerable rework and optimisation of our early boot code to
reduce the need for cache maintenance and avoid jumping in and out
of the kernel when handling relocation under KASLR
- Support for disabling SVE and SME support on the kernel
command-line
- Support for the Hisilicon HNS3 PMU
- Miscellanous cleanups, trivial updates and minor fixes"

Some configs can obviously be removed when sync'ing with savedefconfig, as
follows:
- config SECCOMP was changed to def_bool y in commit 282a181b1a0d ("
seccomp: Move config option SECCOMP to arch/Kconfig"), so no need to
explicitly enable in the defconfig.
- config MAILBOX is already selected by some drivers enabled in the
defconfig, so no need to explicitly enable.
- config QRTR was enabled in the defconfig from commit 1bdf91fd2ae82 ("
arm64: defconfig: Enable Qualcomm QRTR"). However until many kernel
versions later in commit 231a136fdf46 ("arm64: defconfig: enable ath11k
driver"), no driver depended on config QRTR - not for building anyway.
In commit 231a136fdf46, config ATH11K_PCI was enabled and this selects
config QRTR, so there is no need to explicitly enable in the defconfig.

Even if we are now able to tell the kernel to avoid exposing SVE/SME
from the command line, we still have a couple of places where we
unconditionally access the ZCR_EL1 (resp. SMCR_EL1) registers.
On systems with broken firmwares, this results in a crash even if
arm64.nosve (resp. arm64.nosme) was passed on the command-line.
To avoid this, only update cpuinfo_arm64::reg_{zcr,smcr} once
we have computed the sanitised version for the corresponding
feature registers (ID_AA64PFR0 for SVE, and ID_AA64PFR1 for
SME). This results in some minor refactoring.

A number of Kconfig options have moved around in the defconfig

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.
This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.
Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

Since commit:
a004393f45d9a55e ("arm64: idreg-override: use early FDT mapping in ID map")
Kernels built with KASAN_INLINE=y die early in boot before producing any
console output. This is because the accesses made to the FDT (e.g. in
generic string processing functions) are instrumented with KASAN, and
with KASAN_INLINE=y any access to an address in TTBR0 results in a bogus
shadow VA, resulting in a data abort.
This patch fixes this by reverting commits:
7559d9f97581654f ("arm64: setup: drop early FDT pointer helpers")
bd0c3fa21878b6d0 ("arm64: idreg-override: use early FDT mapping in ID map")
... and using the TTBR1 fixmap mapping of the FDT.
Note that due to a later commit:
b65e411d6cc2f12a ("arm64: Save state of HCR_EL2.E2H before switch to EL1")
... which altered the prototype of init_feature_override() (and
invocation from head.S), commit bd0c3fa21878b6d0 does not revert
cleanly, and I've fixed that up manually.

When we added support for AT_HWCAP2 we took advantage of the fact that we
have limited hwcaps to the low 32 bits and stored it along with AT_HWCAP
in a single unsigned integer. Thanks to the ever expanding capabilities of
the architecture we have now allocated all 64 of the bits in an unsigned
long so in preparation for adding more hwcaps convert elf_hwcap to be a
bitmap instead, with 64 bits allocated to each AT_HWCAP.
There should be no functional change from this patch.

THP_SWAP has been proven to improve the swap throughput significantly
on x86_64 according to commit bd4c82c22c367e ("mm, THP, swap: delay
splitting THP after swapped out").
As long as arm64 uses 4K page size, it is quite similar with x86_64
by having 2MB PMD THP. THP_SWAP is architecture-independent, thus,
enabling it on arm64 will benefit arm64 as well.
A corner case is that MTE has an assumption that only base pages
can be swapped. We won't enable THP_SWAP for ARM64 hardware with
MTE support until MTE is reworked to coexist with THP_SWAP.
A micro-benchmark is written to measure thp swapout throughput as
below,
unsigned long long tv_to_ms(struct timeval tv)
{
return tv.tv_sec * 1000 + tv.tv_usec / 1000;
}
main()
{
struct timeval tv_b, tv_e;;
#define SIZE 400*1024*1024
volatile void *p = mmap(NULL, SIZE, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
if (!p) {
perror("fail to get memory");
exit(-1);
}
madvise(p, SIZE, MADV_HUGEPAGE);
memset(p, 0x11, SIZE); /* write to get mem */
gettimeofday(&tv_b, NULL);
madvise(p, SIZE, MADV_PAGEOUT);
gettimeofday(&tv_e, NULL);
printf("swp out bandwidth: %ld bytes/ms\n",
SIZE/(tv_to_ms(tv_e) - tv_to_ms(tv_b)));
}
Testing is done on rk3568 64bit Quad Core Cortex-A55 platform -
ROCK 3A.
thp swp throughput w/o patch: 2734bytes/ms (mean of 10 tests)
thp swp throughput w/ patch: 3331bytes/ms (mean of 10 tests)

Cortex-A57 and Cortex-A72 have an erratum where an interrupt that
occurs between a pair of AES instructions in aarch32 mode may corrupt
the ELR. The task will subsequently produce the wrong AES result.
The AES instructions are part of the cryptographic extensions, which are
optional. User-space software will detect the support for these
instructions from the hwcaps. If the platform doesn't support these
instructions a software implementation should be used.
Remove the hwcap bits on affected parts to indicate user-space should
not use the AES instructions.

When the NUMA nodes are sorted by checking ACPI SRAT (GICC AFFINITY)
sub-table, it's impossible for acpi_map_pxm_to_node() to return
any value, which is greater than or equal to MAX_NUMNODES. Lets drop
the unnecessary check in acpi_numa_gicc_affinity_init().
