[SCSI] qla2xxx: Correct QUEUE_FULL handling.

- Ramp-up I/Os after throttling.
- Consolidate completion-status handling of CS_QUEUE_FULL with
CS_COMPLETE as ISP24xx firmware no longer reports
CS_QUEUE_FULL.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state. This issue can result in a hung PCIe
link. Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.
In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully. In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.

Thanks to James Smart for the inspiration.
Stall error handler if attempting recovery while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.

VirtDevice is removed when fc transport removes a target.

IB/cm: Send DREP in response to unmatched DREQ
Currently a DREP is only sent in response to a DREQ if a connection
has been found matching the DREQ, and it is in the proper state. Once
a DREP is sent, the local connection moves into timewait. Duplicate
DREQs received while in this state result in re-sending the DREP.
However, it's likely that the local connection will enter and exit
timewait before the remote side times out a lost DREP and resends a DREQ.
To handle this, we send a DREP in response to a DREQ, even if a local
connection is not found. This avoids maintaining disconnected
id's in timewait states for excessively long times, just to handle a
lost DREP.

IB/cm: Fix timewait crash after module unload
If the ib_cm module is unloaded while id's are still in timewait, the
CM will destroy the work queue used to process timewait. Once the
id's exit timewait, their timers will fire, leading to a crash trying
to access the destroyed work queue.
We need to track id's that are in timewait, and cancel their deferred
work on module unload.

IB/srp: Enable multiple connections to the same target
Enable multiple concurrent connections to the same SRP target:
1) Use port GUID instead of node GUID in the initiator port
identifier. This allows connections to be made from multiple HCA
ports at the same time.
2) Let the user specify the identifier extention when adding the
device. This allows userspace to make multiple connections even
from the same port, if it wants too.
Without this, only one connection can be made from any given HCA, even
if it has multiple ports, because we don't use multi-channel mode, so
targets will only allow one connection from a given initiator port ID.

adding platform_driver... which I missed. Thus it still used struct
device, causing crashes when hitting sleep/wakeup callbacks (it happened
to work by luck so far, until early/late callbacks got added). This
causes crashes on sleep/wakeup on PowerBooks with 2.6.19. The patch
fixes it by using a proper platform_driver.

[POWERPC] Fix secondary CPU startup on old "powersurge" SMP powermacs
On the old "powersurge" SMP powermacs, the second CPU is started up
by sending it an IPI, which has the side effect of stopping the
timebase clock (so the secondary CPU's timebase can be synchronized
with the primary's). The routine that did this used udelay, which
will hang forever when the timebase is stopped, since udelay now spins
until the timebase reaches a certain value.
The end result is that the kernel would hang when bringing up the
second CPU. This fixes it by using a simple loop which just does a
fixed number of iterations to generate the delay. These old systems
were all clocked at around 200 MHz or so, so a fixed number of
iterations is acceptable.
The IDE driver will pick up the PCI IRQ for both channels on Maple
despite the fact that it's in legacy mode. This works around it by
"hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured
in legacy mode on the Maple platform, thus causing the driver to call
pci_get_legacy_ide_irq() which will return the correct interrupts for
both channels.
