Subject: [PATCH v6 0/3] CET fix patches for nested guest

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 v6:
- Add check for nested vm_entry_controls without VM_ENTRY_LOAD_CET_STATE set
  to snapshot L1's CET states for L2.


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
