KVM: s390: add gib_alert_irq_handler()
The patch implements a handler for GIB alert interruptions
on the host. Its task is to alert guests that interrupts are
pending for them.
A GIB alert interrupt statistic counter is added as well:
$ cat /proc/interrupts
CPU0 CPU1
...
GAL: 23 37 [I/O] GIB Alert
...
