This is a backport to v4.19 of the arm64 patches that exists in mainline to support CPUs that implement the SSBS capability, which gives the OS and user space control over whether Speculative Store Bypass is permitted in certain contexts. This gives a substantial performance boost on hardware that implements it.
At the same time, this series backports arm64 support for reporting of vulnerabilities via syfs. This is covered by the same series since it produces a much cleaner backport, where none of the patches required any changes beyond some manual mangling of the context to make them apply.
Build tested using a fair number of randconfig builds. Boot tested under KVM and on ThunderX2.
All now queued up, thanks.
Thanks Greg.
