[Xen-devel] [PATCH 12/18] xen: initialize irq 0 too
From: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
Impact: theoretical bugfix, cleanup
IRQ 0 is valid, so make sure it gets initialized properly too.
(Though in practice it doesn't matter, because its the timer
interrupt we don't use.)
Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
