[PATCH v2 0/5] Basic Speculation Control feature support

[David Woodhouse]

Baby steps... this is just the basic CPUID and MSR definitions for AMD 
and Intel, followedby the complete no-brainer: Disable KPTI on Intel 
CPUs which set the RDCL_NO bit to say that they don't need it.

David Woodhouse (5):
  x86/cpufeatures: Add CPUID_7_EDX CPUID leaf
  x86/cpufeatures: Add Intel feature bits for Speculation Control
  x86/cpufeatures: Add AMD feature bits for Speculation Control
  x86/msr: Add definitions for new speculation control MSRs
  x86/pti: Do not enable PTI on fixed Intel processors
