Modify intialization semantics:
- perform basic hardware configuration only (as usual)
- allocate resources
- load and execute firmware
- defer link (transport) negotiations to the DPC thread
- again the code in qla2x00_initialize_adapter() to stall probe()
completion was needed for legacy-style scanning.
- DPC thread stalls until probe() complete.
- before probe() completes, set DPC flags to perform loop-resync logic
(similar to what's done during cable-insertion/removal).
Benefits: user does not have to wait 20+ seconds in case the FC cable
is unplugged during driver load, code consolidation (removal of
redundant link negotiation logic during initialize_adaoter()), and
finilly, the driver no longer needs to defer the fc_remote_port_add()
calls to hold off lun-scanning prior to returning from the probe()
function.

If a driver can find its own targets, it can now fill in scan_finished and
(optionally) scan_start in the scsi_host_template. Then, when it calls
scsi_scan_host(), it will be called back (from a thread if asynchronous
discovery is enabled), first to start the scan, and then at intervals to
check if the scan is completed.
Also make scsi_prep_async_scan and scsi_finish_async_scan static.

Received from Mark Salyzyn:
Add code to abort outstanding management ioctl fibs when the blinkLED recovery
is performed. This code is 'clunky' and does not have any real feedback in that
the reset could progress before the user application has gotten it's
notification of command completion. We put a schedule() call to delay just the
right amount for most cases, because we tried a spin and still managed to find
cases where we would spin forever waiting for the management application to
acknowledge the impending doom surrounding the cause of the BlinkLED. Will
cause an oops in the context of the management application if we proceed too
quickly. I view this as the lesser of many evils since currently if there are
outstanding management ioctls during a need to reset/recover the adapter, the
management application just locks up and waits forever. The best practices fix
for this problem not going to be simple or easy (at least the fixes I imagine
today); and we found a balance between the needs of the driver to proceed, and
the applications that locked or confused that would hold back the driver. I
just do not like the idea of a kernel oops in an application to deal with low
priority, sluggish or misbehaving applications.

If an ipr adapter hits a fatal microcode error requiring a reset
while a SATA device is going through EH, it can result in a command

can cause PCI bus errors. Wait for any outstanding adapter reset
to finish prior to issuing a SATA device reset.

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.

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.

This is a quick hack to overcome the fact that SRCU currently does not
allow static initializers, and we need to sometimes initialize those
things before any other initializers (even "core" ones) can do so.
Currently we don't allow this at all for modules, and the only user that
needs is right now is cpufreq. As reported by Thomas Gleixner:

This reverts commit 37605a6900.
Again.
This same bug has now been introduced twice: it was done earlier by
commit b8d35192c5, only to be reverted
last time in commit 72945b2b90.
We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.
Keeping events within the one deferred execution thread automatically
throttles the events properly.
At least the Compaq N620c will lock up completely on the first thermal
event without this patch reverted.

Benh points out that the msgs[0].flags entry never got initialized, and
since it's an automatic stack allocation, it could have any random
value, which is bad.
Rewrite the initializer to explicitly initialize all fields of the small

handle msgs[1].buf in the same initializer while we're at it, instead of
initializing that one separately later.
