RE: [PATCH v2] mce: use safe MSR accesses

[Luck, Tony]

-				 rdmsrl(msrs[i], val);
-
-				 /* CntP bit set? */
-				 if (val & BIT_64(62)) {
-					val &= ~BIT_64(62);
-					wrmsrl(msrs[i], val);
-				 }
+				 /* Clear CntP bit safely */
+				 msr_clear_bit(msrs[i], 62);

Very nice! Clean solution with less lines of code than the original.
