Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:

- MTE asynchronous support for KASan. Previously only synchronous
(slower) mode was supported. Asynchronous is faster but does not
allow precise identification of the illegal access.

- Run kernel mode SIMD with softirqs disabled. This allows using NEON
in softirq context for crypto performance improvements. The
conditional yield support is modified to take softirqs into account
and reduce the latency.

- Preparatory patches for Apple M1: handle CPUs that only have the VHE
mode available (host kernel running at EL2), add FIQ support.

- arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers,
new functions for the HiSilicon HHA and L3C PMU, cleanups.

- Re-introduce support for execute-only user permissions but only when
the EPAN (Enhanced Privileged Access Never) architecture feature is
available.

- Disable fine-grained traps at boot and improve the documented boot
requirements.

- Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).

- Add hierarchical eXecute Never permissions for all page tables.

- Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
to control which PAC keys are enabled in a particular task.

- arm64 kselftests for BTI and some improvements to the MTE tests.

- Minor improvements to the compat vdso and sigpage.

- Miscellaneous cleanups.

arm64: mte: Enable TCO in functions that can read beyond buffer limits

load_unaligned_zeropad() and __get/put_kernel_nofault() functions can
read past some buffer limits which may include some MTE granule with a
different tag.

When MTE async mode is enabled, the load operation crosses the boundaries
and the next granule has a different tag the PE sets the TFSR_EL1.TF1 bit
as if an asynchronous tag fault is happened.

Enable Tag Check Override (TCO) in these functions before the load and
disable it afterwards to prevent this to happen.

Note: The same condition can be hit in MTE sync mode but we deal with it
through the exception handling.
In the current implementation, mte_async_mode flag is set only at boot
time but in future kasan might acquire some runtime features that
that change the mode dynamically, hence we disable it when sync mode is
selected for future proof.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:

- vDSO build improvements including support for building with BSD.

- Cleanup to the AMU support code and initialisation rework to support
cpufreq drivers built as modules.

- Removal of synthetic frame record from exception stack when entering
the kernel from EL0.

- Add support for the TRNG firmware call introduced by Arm spec
DEN0098.

- Cleanup and refactoring across the board.

- Avoid calling arch_get_random_seed_long() from
add_interrupt_randomness()

- Perf and PMU updates including support for Cortex-A78 and the v8.3
SPE extensions.

- Significant steps along the road to leaving the MMU enabled during
kexec relocation.

- Faultaround changes to initialise prefaulted PTEs as 'old' when
hardware access-flag updates are supported, which drastically
improves vmscan performance.

- CPU errata updates for Cortex-A76 (#1463225) and Cortex-A55
(#1024718)

- Preparatory work for yielding the vector unit at a finer granularity
in the crypto code, which in turn will one day allow us to defer
softirq processing when it is in use.

- Support for overriding CPU ID register fields on the command-line.
