One typo in commit: "KVM: convert custom marker based tracing to event traces" caused: set_cr8: #GP, reserved bits 0x7f when try to boot up IA32e Windows guest. One value has been written to R8 instead of specific register, then the value of specific register can be invalid as CR8. Guest RMW it, then got trouble.
