In fact, "NOEXCP" can be used in the initialization for the deferred
and UCNA table entries. But it may affect the following snippet in
do_machine_check().
/*
* When machine check was for corrected/deferred handler don't
* touch, unless we're panicing.
*/
if ((severity == MCE_KEEP_SEVERITY ||
severity == MCE_UCNA_SEVERITY) && !no_way_out)
continue;
If `no_way_out' equals 1, we may need to dump/decode corrected/deferred
error information. So if we use "NOEXCP" to initialize the deferred and
UCNA table entries, do_machine_check will skip checking deferred/UCNA
entry when `no_way_out' is set to 1.
thx!
