Symptoms:
	PHKL_29951:
	( SR:8606326241 CR:JAGae88526 )
	If multiple Machine Check Aborts (MCAs) occur
	simultaneously when running HP-UX 11i v2 there is a
	possibility that not all the SAL MCA error records will be
	passed to diag2 driver, resulting in missing files in the
	/var/tombstone" directory the next time the system is
	booted. This will prevent support from properly analyzing
	the cause of the MCAs.

Defect Description:
	PHKL_29951:
	( SR:8606326241 CR:JAGae88526 )
	The booting monarch processor is not passing all possible
	logs to the diag2 driver, passing only the last log
	received.  This is due to the fact that when we are
	gathering the logs for the monarch processor and passing
	them to the diag2 driver the diag2 driver in not installed.
	All logs, other than the last log, are lost.

	Resolution:
	Modify kernel to loop through and pass each log to
	diagnostics later in boot when we know the driver is
	installed.  This can be done by not calling MCA_boottime
	logging during MCA_enable for the monarch.  We will call
	MCA_boottime logging for the monarch after drivers are
	installed so we know the diag2 driver gets all of the logs.

Enhancement:
	No
