Bugzilla: 242124
Message-Id: <4667B455.5000608@redhat.com>
Changelog: [xen] ia64: Fix HVM interrupts on IPF


bz242124
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242124

Backport of cset#12441.

Xen has changed to set-irq-level hypercall from shared-memory
PIC stat.  This patch makes ia64 kernel accommodate this change.
Without this, HVM domain does not work because any interruption
are not risen.

Thanks,
Kei
