[PATCH] ips driver 4/6
This is by far the biggest patch. It is a rewrite of the
driver's horrid locking. In addition to the host_lock,
the driver used to have 4 other locks per adapter!
It had a redundant ha_lock and a lock for each of 3
queues. In a few places it also played with atomic bit
setting. And almost all of it was useless as the
host_lock was already held.
This patch cleans up this locking nightmare. The driver
now uses the host_lock exclusively. Only a few places
needed to add calls to lock the host_lock. Most of
this patch is deletion of useless extra locking.
