Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon: "The main changes are relating to our handling of access/dirty bits, where our low-level page-table helpers could lead to stale young mappings and loss of the dirty bit in some cases (the latter has not been observed in practice, but could happen when clearing "soft-dirty" if we enabled that). These were posted as part of a larger series, but the rest of that is less urgent and needs a v2 which I'll get to shortly. In other news, we've now got a set of fixes to resolve the lockdep/tracing problems that have been plaguing us for a while, but they're still a bit "fresh" and I plan to send them to you next week after we've got some more confidence in them (although initial CI results look good). Summary: - Fix kerneldoc warnings generated by ACPI IORT code - Fix pte_accessible() so that access flag is ignored - Fix missing header #include - Fix loss of software dirty bit across pte_wrprotect() when HW DBM is enabled" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: pgtable: Ensure dirty bit is preserved across pte_wrprotect() arm64: pgtable: Fix pte_accessible() ACPI/IORT: Fix doc warnings in iort.c arm64/fpsimd: add <asm/insn.h> to <asm/kprobes.h> to fix fpsimd build
