[Linux-ia64] fix for test8 kernel

[Linux-ia64] fix for test8 kernel

[David Mosberger]

The attached patch fixes the problem that caused grief on some
machines (primarily B1 Big Surs, it seems).  The problem showed itself
as an infinite stream of "unexpected irq 0" messages.  The fix is due
to Asit Mallick and fixes a problem I created when I goofed in
applying another patch.
