Apparently these are the only drives that try to negotiate IU and QAS
at u160 speeds. The aic7xxx driver can't cope with this. The fix is
to eliminate the IU and QAS setting routines. I've #if 0'd them out,
just in case we ever get the sequencer documentation out of Adaptec,
since we'd then be able to fix the driver.

Analysis:
Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which
reads psli->mbox_active to determine the timeout mbox. Timeout
handler then NULL's psli->mbox_active and calls
lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls
link_down(). link_down() now calls disc_done() which calls
mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which
goes back to read psli->mbox_active which is already NULL'ed.
Remove redundant if statement in lpfc_mbox_timeout_handler. pmbox is
assigned psli->mbox_active so there is no need to check if it actually
equals psli->mbox_active.

1. Establish a simple API for process freezing defined in linux/include/sched.h:
frozen(process) Check for frozen process
freezing(process) Check if a process is being frozen
freeze(process) Tell a process to freeze (go to refrigerator)
thaw_process(process) Restart process
frozen_process(process) Process is frozen now
2. Remove all references to PF_FREEZE and PF_FROZEN from all
kernel sources except sched.h
3. Fix numerous locations where try_to_freeze is manually done by a driver
4. Remove the argument that is no longer necessary from two function calls.
5. Some whitespace cleanup
6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
cleared before setting PF_FROZEN, recalc_sigpending does not check
PF_FROZEN).
This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!
