x86: fix IRQ migration when using directed EOI (broken with c/s 20465)
In directed-EOI mode, there is no chance to do the migration in
mask_and_ack_level_ioapic_irq(), as the remote IRR bit can''t
possibly
be clear after issuing the EOI to the LAPIC. Consequently,
there''s no
point to even try. Instead, migration must be done in
end_level_ioapic_irq(), and it requires masking the interrupt source
prior to issuing the EOI to the IO-APIC.

Yes, I''m afraid they are. And the reports of regressions, too. There
was an infrastructure problem here.
I''ve updated the bisector to insist on a "stripey in time"
pattern of
reproductions before blaming a particular changeset, which should make
these false accusations much less frequent. However my change to the
test harness is currently still being tested to make sure that it
doesn''t break anything before it gets pushed to live ...
Ian.
