	SUBTTL LLMOP PSI queue

COMMENT $
Nota bene - Once upon a time, LLMOP did some nasty things. It called
PSIRQ at interrupt level. This caused GLFNF BUGHLTs, SUMNR1 BUGCHKs,
and UNBFNF BUGCHKs. This is not good. So now, there is a queue for
LLMOP to queue up PSI requests. It looks something like this:

LLMPSQ/  ENTRY1 ------>+
                       |
                       +----> ENTRY1+.FLPSI/ Pointer to next entry ---...
                              ENTRY1+.CHNFK/ channel,,fork

		LLMOP PSI queue entry
	+--------------------------------------------------+
.FLPSI	|  Forward pointer to the next entry in the queue  |
	+--------------------------------------------------+
.CHNFK	|  Channel number for PSI | Fork number to get PSI |
	+--------------------------------------------------+
