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
   ...

The only thing that bother me is the short timer's expiration value.
But it is optimization and it is working for me so.
