Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"The main theme of this pull request is security covering variants 2
and 3 for arm64. I expect to send additional patches next week
covering an improved firmware interface (requires firmware changes)
for variant 2 and way for KPTI to be disabled on unaffected CPUs
(Cavium's ThunderX doesn't work properly with KPTI enabled because of
a hardware erratum).
Summary:
- Security mitigations:
- variant 2: invalidate the branch predictor with a call to
secure firmware
- variant 3: implement KPTI for arm64
- 52-bit physical address support for arm64 (ARMv8.2)
- arm64 support for RAS (firmware first only) and SDEI (software
delegated exception interface; allows firmware to inject a RAS
error into the OS)
- perf support for the ARM DynamIQ Shared Unit PMU
- CPUID and HWCAP bits updated for new floating point multiplication
instructions in ARMv8.4
- remove some virtual memory layout printks during boot
- fix initial page table creation to cope with larger than 32M kernel
images when 16K pages are enabled"
