SubjectRe: [RFC PATCH] x86, mce: change the mce notifier to 'blocking' from 'atomic'

No, it isn't. We're calling it in normal process context in
mce_gen_pool_process() too.

So this early exit will avoid any sleeping in atomic context. And since
there's nothing you can do about the errors reported in atomic context,
we can actually use that fact.
