Linus Torvalds 0df072ab65 Take care of a race between when the #VC exception is raised and when

the guest kernel gets to emulate certain instructions in SEV-{ES,SNP}
 guests by:
 
 - disabling emulation of MMIO instructions when coming from user mode
 
 - checking the IO permission bitmap before emulating IO instructions and
   verifying the memory operands of INS/OUTS insns.
