[PATCH] qla4xxx: bug fix: driver hardware semaphore needs to be grabbed before soft reset
On qla4xxx, the driver needs to grab the drvr semaphore provided by
the hardware, prior to issuing a reset. This patches takes care of a
couple of places where it was not being done. In addition there is
minor clean up.

[PATCH] aic94xx: delete ascb timers when freeing queues
When the aic94xx driver creates ascbs, each ascb is initialized with a
timeout timer. If there are any ascbs left over when the driver is being
torn down, these timers need to be deleted. In particular, we seem to
hit this case when ascbs are issued yet never end up on the done list.
Right now there's a sequencer bug that results in this happening every
so often.
CONTROL PHY commands are typically sent when things are really messed
up with the sequencer; however, any other leftover ascb should produce
loud warnings.

[PATCH] aic94xx: handle REQ_DEVICE_RESET
This patch implements a REQ_DEVICE_RESET handler for the aic94xx
driver. Like the earlier REQ_TASK_ABORT patch, this patch defers the
device reset to the Scsi_Host's workqueue, which has the added benefit
of ensuring that the device reset does not happen at the same time
that the abort tmfs are being processed. After the phy reset, the
busted drive should go away and be re-detected later, which is indeed
what I've seen on both a x260 and a x206m.

The root cause is that some irq_chip variables, especially ia64_msi_chip,
initiate their memeber end to point to NULL. __do_IRQ doesn't check
if irq_chip->end is null and just calls it after processing the interrupt.
As irq_chip->end is called at many places, so I fix it by reinitiating
irq_chip->end to dummy_irq_chip.end, e.g., a noop function.
The root cause is the device struct is initialized twice.
If the device is allocated dynamically by platform_device_alloc,
platform_device_alloc will initialize struct device, then,
platform_device_add should be used to register the device.
The difference between platform_device_register and platform_device_add is
platform_device_register will initiate the device while platform_device_add
won't.
