Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon: "These are almost exclusively related to CPU errata in CPUs from Broadcom and Qualcomm where the workarounds were either not being enabled when they should have been or enabled when they shouldn't have been. The only "interesting" fix is ensuring that writeable, shared mappings are initially mapped as clean since we inadvertently broke the logic back in v4.14 and then noticed the problem via code inspection the other day. The only critical issue we have outstanding is a sporadic NULL dereference in the scheduler, which doesn't appear to be arm64-specific and PeterZ is tearing his hair out over it at the moment. Summary: - Enable CPU errata workarounds for Broadcom Brahma-B53 - Enable CPU errata workarounds for Qualcomm Hydra/Kryo CPUs - Fix initial dirty status of writeable, shared mappings" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: apply ARM64_ERRATUM_843419 workaround for Brahma-B53 core arm64: Brahma-B53 is SSB and spectre v2 safe arm64: apply ARM64_ERRATUM_845719 workaround for Brahma-B53 core arm64: cpufeature: Enable Qualcomm Falkor errata 1009 for Kryo arm64: cpufeature: Enable Qualcomm Falkor/Kryo errata 1003 arm64: Ensure VM_WRITE|VM_SHARED ptes are clean by default
