Pull arm64 fixes from Will Deacon:
"A couple of late fixes here, but one that we've been sitting on for a
few weeks while the details were worked out. Specifically, we now
enforce USER_DS on taking exceptions whilst in the kernel, which
avoids leaking kernel data to userspace through things like perf. The
other patch is an update to a workaround for a hardware erratum on
some Cavium SoCs.
Summary:
- Enforce USER_DS on exception entry from EL1
- Apply workaround for Cavium errata #27456 on Thunderx-81xx parts"
