Pull x86/pti updates from Thomas Gleixner:
"Another set of melted spectrum updates:
- Iron out the last late microcode loading issues by actually
checking whether new microcode is present and preventing the CPU
synchronization to run into a timeout induced hang.
- Remove Skylake C2 from the microcode blacklist according to the
latest Intel documentation
- Fix the VM86 POPF emulation which traps if VIP is set, but VIF is
not. Enhance the selftests to catch that kind of issue
- Annotate indirect calls/jumps for objtool on 32bit. This is not a
functional issue, but for consistency sake its the right thing to
do.
- Fix a jump label build warning observed on SPARC64 which uses 32bit
storage for the code location which is casted to 64 bit pointer w/o
extending it to 64bit first.
- Add two new cpufeature bits. Not really an urgent issue, but
provides them for both x86 and x86/kvm work. No impact on the
current kernel"
