Andi Kleen 8f4e956b31 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.
