Pull arm64 fixes from Catalin Marinas: "Mostly fixes apart from the kprobe blacklist checking which was deferred because of conflicting with a fix merged after I pinned the arm64 for-next/core branch (f2b3d8566d81 "arm64: kprobe: Always blacklist the KVM world-switch code"). Summary: - Update the kprobe blacklist checking for arm64. This was supposed to be queued during the merging window but, due to conflicts, it was deferred post -rc1 - Extend the Fujitsu erratum 010001 workaround to A64FX v1r0 - Whitelist HiSilicon Taishan v110 CPUs as not susceptible to Meltdown - Export save_stack_trace_regs() - Remove obsolete selection of MULTI_IRQ_HANDLER" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: remove obsolete selection of MULTI_IRQ_HANDLER arm64: kpti: Whitelist HiSilicon Taishan v110 CPUs arm64: Add MIDR encoding for HiSilicon Taishan CPUs arm64/stacktrace: Export save_stack_trace_regs() arm64: apply workaround on A64FX v1r0 arm64: kprobes: Use arch_populate_kprobe_blacklist() arm64: kprobes: Move exception_text check in blacklist arm64: kprobes: Remove unneeded RODATA check arm64: kprobes: Move extable address check into arch_prepare_kprobe()
