The irq_set_affinity() call in setup_ipapic_dest() that the commit

replaces was introduced in commit
aa5cb97f14a2dd5aefabed6538c35ebc087d7c24
I built a kernel at aa5cb97f14a2dd5aefabed6538c35ebc087d7c24 with
the cherry-pick 4857c91f0d195f05908fff296ba1ec5fca87066c and it
worked fine. I conclude that the bug was introduced somewhere in
between and aa5cb97f14a2dd5aefabed6538c35ebc087d7c24 exposed it.
I shall try and bisect again, cherry-picking
4857c91f0d195f05908fff296ba1ec5fca87066c
at every iteration to expose the underlying bug.
That may take a while.
