Subject: [PATCH 6/6]: SN Hotplug Driver - PREEMPT/pcibus_info fix
Date: Mon, 02 May 2005 12:50:30 +0000 [thread overview]
Message-ID: <42762216.5010303@sgi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 0 bytes --]
[-- Attachment #2: pcibus_info.patch-6 --]
[-- Type: text/plain, Size: 876 bytes --]
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.
