[PATCH] alpha: SMP IRQ routing fix

From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>

After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.

Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly.  As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.

Fixed basically by s/cpu_present_mask/cpu_present_map/.

Thanks to Ernst Herzberg for reporting the bug and testing the fix.
