From c7d2d28b9851d0ffc9924b0e36bac806d18ebf25 Mon Sep 17 00:00:00 2001 From: Ivan Kokshaysky Date: Sun, 4 Jun 2006 02:51:34 -0700 Subject: [PATCH] alpha: SMP IRQ routing fix From: Ivan Kokshaysky 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.
