Routine Description:
This routine is called to process the list of registered Non-Maskable-
Interrupt (NMI) handlers in the system. This routine is called from
the NMI interrupt vector, the IRQL is unknown and must be treated as
if at HIGH_LEVEL. Neither this function or any called function can
alter system IRQL.
The list of handlers must be edited in such a way that it is always
valid. This routine cannot acquire a lock before transiting the list.
Arguments:
None.
Return Value:
Returns TRUE is any handler on the list claims to have handled the
interrupt, FALSE otherwise.
