Hi,

Christian has reported that one can make a TCG guest stuck by running
PRNO TRNG with a huge buffer. This series fixes this by making PRNO
TRNG end on cpu_loop_exit_requested().

Patch 1 is the fix, patch 2 is the test.

Cc: Harald, because this may conflict with the CPACF series.

Best regards,
Ilya
