From 7fe4c1b16854f0440939c62b8102cbf5c75e7cdc Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Wed, 6 Jul 2005 15:30:25 -0700 Subject: [IA64] hotplug/ia64: SN Hotplug Driver - PREEMPT/pcibus_info fix This patch fixes an issue with the PROM and a kernel running with CONFIG_PREEMPT enabled. When CONFIG_PREEMPT is enabled, the size of a spinlock_t changes -- resulting in the PROM writing to an incorrect location.
