KVM: x86: allow RSM from 64-bit mode The SDM says that exiting system management mode from 64-bit mode is invalid, but that would be too good to be true. But actually, most of the code is already there to support exiting from compat mode (EFER.LME=1, EFER.LMA=0). Getting all the way from 64-bit mode to real mode only requires clearing CS.L and CR4.PCIDE.
