From b2c03941b50944a268ee4d5823872f220809a3ba Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Wed, 6 Dec 2006 20:41:00 -0800 Subject: [PATCH] IPMI: Allow hot system interface remove This modifies the IPMI driver so that a lower-level interface can be dynamically removed while in use so it can support hot-removal of hardware. It also adds the ability to specify and dynamically change the IPMI interface the watchdog timer and the poweroff code use.
