Subject: [PATCH 0/2] KVM: nVMX: msr bitmaps fixes

Jim found several bugs that allowed L2 to read L0's x2APIC MSRs and write to
TPR, EOI, and SELF_IPI, in the worst case.

The fix is split into two patches as possible causes were introduced by
two different commits.

I have not Cc'd stable as the patches are quite long and nVMX is not
considered to be ready for production, yet.

Radim Krčmář (2):
  KVM: nVMX: fix msr bitmaps to prevent L2 from accessing L0 x2APIC
  KVM: nVMX: postpone VMCS changes on MSR_IA32_APICBASE write
