From bd9e5eefecb3d69018bb95796298019d309cbec8 Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Tue, 10 May 2011 19:28:41 +0000 Subject: [PATCH] powerpc/kdump64: Don't reference freed memory as pacas Starting with 1426d5a3bd07589534286375998c0c8c6fdc5260 (powerpc: Dynamically allocate pacas) the space for pacas beyond cpu_possible is freed, but we failed to update the loop in crash.c. Since c1854e00727f50f7ac99e98d26ece04c087ef785 (powerpc: Set nr_cpu_ids early and use it to free PACAs) the number of pacas allocated is always nr_cpu_ids.
