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

Pull arm64 updates from Catalin Marinas:

- arm64 support for syscall emulation via PTRACE_SYSEMU{,_SINGLESTEP}

- Wire up VM_FLUSH_RESET_PERMS for arm64, allowing the core code to
manage the permissions of executable vmalloc regions more strictly

- Slight performance improvement by keeping softirqs enabled while
touching the FPSIMD/SVE state (kernel_neon_begin/end)

- Expose a couple of ARMv8.5 features to user (HWCAP): CondM (new
XAFLAG and AXFLAG instructions for floating point comparison flags
manipulation) and FRINT (rounding floating point numbers to integers)

- Re-instate ARM64_PSEUDO_NMI support which was previously marked as
BROKEN due to some bugs (now fixed)

- Improve parking of stopped CPUs and implement an arm64-specific
panic_smp_self_stop() to avoid warning on not being able to stop
secondary CPUs during panic

- perf: enable the ARM Statistical Profiling Extensions (SPE) on ACPI
platforms

- perf: DDR performance monitor support for iMX8QXP

- cache_line_size() can now be set from DT or ACPI/PPTT if provided to
cope with a system cache info not exposed via the CPUID registers

- Avoid warning on hardware cache line size greater than
ARCH_DMA_MINALIGN if the system is fully coherent

- arm64 do_page_fault() and hugetlb cleanups

- Refactor set_pte_at() to avoid redundant READ_ONCE(*ptep)

- Ignore ACPI 5.1 FADTs reported as 5.0 (infer from the
'arm_boot_flags' introduced in 5.1)

- CONFIG_RANDOMIZE_BASE now enabled in defconfig

- Allow the selection of ARM64_MODULE_PLTS, currently only done via
RANDOMIZE_BASE (and an erratum workaround), allowing modules to spill
over into the vmalloc area

- Make ZONE_DMA32 configurable

ASoC: Updates for v5.3

This is a very big update, mainly thanks to Morimoto-san's refactoring
work and some fairly large new drivers.

- Lots more work on moving towards a component based framework from
Morimoto-san.
- Support for force disconnecting muxes from Jerome Brunet.
- New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant
CX2072X, Realtek RT1011 and RT1308.
