x86/mce: Fix copy/paste error in exception table entries
Back in commit:
92b0729c34cab ("x86/mm, x86/mce: Add memcpy_mcsafe()")
... I made a copy/paste error setting up the exception table entries
and ended up with two for label .L_cache_w3 and none for .L_cache_w2.
This means that if we take a machine check on:
.L_cache_w2: movq 2*8(%rsi), %r10
then we don't have an exception table entry for this instruction
and we can't recover.
Fix: s/3/2/
