For crying out loud, they have devices which do not like port resets.
So, do what usb-storage does and try both bulk and port resets.
We start with a port reset (which usb-storage does at the end of transport),
then do a Bulk reset, then a port reset again. This seems to work for me.
The code is getting dirtier and dirtier here, but I swear that I'll
do something about it (see those two new XXX). Honest.

If SCSI commands are submitted while other commands are still processed,
the dispatch loop turns, and we stop the work_timer. Then, if URB fails
to complete, ub hangs until the device is unplugged.
This does not happen often, becase we only allow one SCSI command per
block device, but does happen (on multi-LUN devices, for example).
The fix is to stop timer only when we actually going to change the state.
The nicest code would be to have the timer stopped in URB callback, but
this is impossible, because it can be called from inside a timer, through
the urb_unlink. Then we get BUG in timer.c:cascade(). So, we do it a
little dirtier.

The blk_cleanup_queue does not necesserily destroy the queue. When we
destroy the corresponding ub_dev, it may leave the queue spinlock pointer
dangling.
This patch moves spinlocks from ub_dev to static memory. The locking
scheme is not changed. These spinlocks are still separate from the ub_lock.

This moves the previously widely-used ehci-pci.c BIOS handoff
code into the pci-quirks.c file, replacing the less widely used
"early handoff" version that seems to cause problems lately.
One notable change: the "early handoff" version always enabled
an SMI IRQ ... and did so even if the pre-Linux code said it was
not using EHCI (and not expecting EHCI SMIs). Looks like a goof
in a workaround for some unknown BIOS version.
This merged version only forcibly enables those IRQs when pre-Linux
code says it's using EHCI. And now it always forces them off "just
in case".

A critical thing the ServeRAID driver MUST do is hide the physical DASDI
devices from the OS. It does this by intercepting the INQUIRY commands.
In recent 2.6.15 testing, I discovered this to be failing.
The cause was the driver assuming that the INQUIRY response data was in a
simple single buffer, when it was actually a 1 element scatter gather list.
This patch makes ips always look at the correct data when examining an
INQUIRY response.

The ioc->alt_ioc->alt_ioc pointer is not getting cleared
during driver unload time. This dangling pointer
can result in panic in certain circumstances, such
as error recovery, or firmware download in flashless
environments. This only impacts dual functions controllers,

This patch also includes a small cosmetic name change

mpt_msi_enable is initialized to 0 implicitly, no need to do that. Also
replace if (mpt_msi_enable == 1) tests with just if (mpt_msi_enable).

The ipw2100 driver misunderstood the parameter of txpower.
Tx Power off means turn off the radio, but the driver interpret it as
"can't set txpower". So when getting the txpower, it sets disabled=1 to
the iwconifg tool in managed mode. And the tool will display "Tx Power off"
when disabled=1.
Now, in managed mode, iwconfig will not show "TX Power" if the radio is not
switched off. It will only display "Tx Power off" only if the radio is killed.

This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver

minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.
