So you don't care which CPU number mce_setup() used because you are
going to update it with the right one from CPER?

Then maybe the fix for part 1 is just to use raw_smp_processor_id() instead of
smp_processor_id() to avoid the warning for calling with pre-emption enabled,
instead of disabling premption with the get_cpu() ... put_cpu() wrap around the
call to mce_setup()?
