[PATCH] ipmi: use refcount in message handler
This patch is rather large, but it really can't be done in smaller chunks
easily and I believe it is an important change. This has been out and tested
for a while in the latest IPMI driver release. There are no functional
changes, just changes as necessary to convert the locking over (and a few
minor style updates).
The IPMI driver uses read/write locks to ensure that things exist while they
are in use. This is bad from a number of points of view. This patch removes
the rwlocks and uses refcounts and RCU lists to manage what the locks did.
