Linux just switched that around for the machine check banks ... if they #GP
fault, then something is seriously wrong.
Maybe that isn't a general change of direction though. Perhaps I
should either use rdmsrl_safe() in this code. Or (better?) add
if (boot_cpu_has(X86_FEATURE_HYPERVISOR))
return;
to the start of intel_imc_init().
