Subject: [PATCH 6/6]: hotplug/ia64: SN Hotplug Driver - PREEMPT/pcibus_info
Message-Id: <42835EC0.5030409@sgi.com>

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.
