Subject: [PATCH v3 0/3] Fix undefined operation VMXOFF during reboot and crash

At the request of Sean Christopherson, the original patch was split
into three patches, each fixing a distinct issue related to the original
bug, of a hang due to VMXOFF causing an undefined operation fault
when the kernel reboots with CR4.VMXE set. The combination of
the patches is the complete fix to the reported bug, and a lurking
error in asm side effects.

David P. Reed (3):
  Correct asm VMXOFF side effects
  Fix undefined operation fault that can hang a cpu on crash or panic
  Force all cpus to exit VMX root operation on crash/panic reliably
