[IA64] Stop using the deprecated __do_IRQ() code path
Thomas Gleixner <tglx@linutronix.de> wrote: >__do_IRQ() has been deprecated after a two years migration phase in >commit 0e57aa1. Since then another 18 months have gone by ... Mostly trivial stuff for this. The only tricky part was realizing that the new handler_*_irq() paths do not use desc->chip->end(irq). Not a problem for the edge case as the ia64 iosapic routine for that was nop(). But the "level" case handled interrupt migration there. Just use a slightly modified version of the "end" routine as "unmask" for the level triggered case. Signed-off-by: Tony Luck <tony.luck@intel.com>
