Subject: [PATCH 0/4] VMX Capability MSRs

This patchset includes v2 of "KVM: nVMX: support restore of VMX capability
MSRs" (patch 1) as well as some additional related patches that came up
while preparing v2.

Patches 2 and 3 make KVM's emulation of MSR_IA32_VMX_CR{0,4}_FIXED1 more
accurate. Patch 4 fixes a bug in emulated VM-entry that came up when
testing patches 2 and 3.

Changes since v1:
  * Support restoring less-capable versions of MSR_IA32_VMX_BASIC,
    MSR_IA32_VMX_CR{0,4}_FIXED{0,1}.
  * Include VMX_INS_OUTS in MSR_IA32_VMX_BASIC initial value.

David Matlack (4):
  KVM: nVMX: support restore of VMX capability MSRs
  KVM: nVMX: fix checks on CR{0,4} during virtual VMX operation
  KVM: nVMX: accurate emulation of MSR_IA32_CR{0,4}_FIXED1
  KVM: nVMX: load GUEST_EFER after GUEST_CR0 during emulated VM-entry
