Linus Torvalds 6304672b7f Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull x86/pti updates from Thomas Gleixner:
 "Another set of melted spectrum related changes:

   - Code simplifications and cleanups for RSB and retpolines.

   - Make the indirect calls in KVM speculation safe.

   - Whitelist CPUs which are known not to speculate from Meltdown and
     prepare for the new CPUID flag which tells the kernel that a CPU is
     not affected.

   - A less rigorous variant of the module retpoline check which merily
     warns when a non-retpoline protected module is loaded and reflects
     that fact in the sysfs file.

   - Prepare for Indirect Branch Prediction Barrier support.

   - Prepare for exposure of the Speculation Control MSRs to guests, so
     guest OSes which depend on those "features" can use them. Includes
     a blacklist of the broken microcodes. The actual exposure of the
     MSRs through KVM is still being worked on"
