x86: Stop MCEs and NMIs during code patching ...
When a machine check or NMI occurs while multiple byte code is patched
the CPU could theoretically see an inconsistent instruction and crash.
Prevent this by temporarily disabling MCEs and returning early in the
NMI handler.
Based on discussion with Mathieu Desnoyers.
