Subject: [PATCH 0/7] KVM: nVMX: Bug fixes and cleanup
Fix for a brutal segment caching bug that manifested as random nested
VM-Enter failures when running with unrestricted guest disabled. A few
more bug fixes and cleanups for stuff found by inspection when hunting
down the caching issue.
Sean Christopherson (7):
KVM: nVMX: Reset the segment cache when stuffing guest segs
KVM: nVMX: Reload vmcs01 if getting vmcs12's pages fails
KVM: nVMX: Explicitly check for valid guest state for !unrestricted
guest
KVM: nVMX: Move free_nested() below vmx_switch_vmcs()
KVM: nVMX: Ensure vmcs01 is the loaded VMCS when freeing nested state
KVM: nVMX: Drop redundant VMCS switch and free_nested() call
KVM: nVMX: WARN on attempt to switch the currently loaded VMCS
