But you proposed setting excp by looking at mcg_status:
> excp = ((m->mcg_status & MCG_STATUS_MCIP) ? EXCP_CONTEXT : NO_EXCP);

Which makes the code rather self referential.  If we actually did arrive in MCE handler
with MCIP == 0 ... then your code would pretend that we'd arrived here from the
poll code, and skip over the test for MCIP - so fail to report that MCIP wasn't set.
