[S390] zcrypt: Fix check to look for facility bits 2 & 65
Fix the check for ap interupts to look for facility bits 2 and 65. Make sure that we only register interrupts for aps, if the machine has ap interrupt support. This patch is relevant only for the 2.6.37 stable series. Cc: stable@kernel.org Signed-off-by: Felix Beck <felix.beck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
