x86/mce: Add infrastructure to support Local MCE
Initialize and prepare for handling LMCEs. Add a boot-time
option to disable LMCEs.
Signed-off-by: Ashok Raj <ashok.raj@intel.com>
[ Simplify stuff, align statements for better readability, reflow comments; kill
unused lmce_clear(); save us an MSR write if LMCE is already enabled. ]
