[PATCH 0/4] KVM: VMX: Add helper+macros to do sec exec adjustment

[Sean Christopherson <sean.j.christopherson@xxxxxxxxx>]

Add a helper function and macro wrappers to consolidate code for adjusting
secondary execution controls based on guest CPUID.  The adjustments are
effectively 10+ lines of copy+paste for each control, with slight tweaks
to account for annoying differences, e.g. XSAVES has additional checks.

Patches 1-3 are prep work to make INVPCID and RDTSCP align with the
"standard" nomenclature so that they don't require special casing.

Sean Christopherson (4):
  KVM: VMX: Rename vmx_*_supported() helpers to cpu_has_vmx_*()
  KVM: VMX: Unconditionally clear CPUID.INVPCID if !CPUID.PCID
  KVM: VMX: Rename RDTSCP secondary exec control name to insert "ENABLE"
  KVM: VMX: Add a helper and macros to reduce boilerplate for sec exec
