This patch series is to fix a few issues found during patch review and
testing on Linux, also including a patch to explictly disable CET support
in nested guest over Hyper-V(s).

change in v4:
- Added guest CET cpuid check before sync vmcs02 CET state to vmcs12.
- Opportunistically added similar fix for MPX.

Yang Weijiang (3):
  KVM: nVMX: Sync L2 guest CET states between L1/L2
  KVM: nVMX: Set X86_CR4_CET in cr4_fixed1_bits if CET IBT is enabled
  KVM: nVMX: Add CET entry/exit load bits to evmcs unsupported list
