If the scsi_alloc_queue or the slave_alloc calls in scsi_alloc_device fail,
we forget to release the locally allocated sdev on the failure path.

On certain systems the driver seems to hit upon some
"scsi0: Invalid Sequencer interrupt occurred." problem and dumps card state.
According to Adaptec engineers this message is harmless. So as not to
confuse user we can as well disable the internal card state dump and
just print out the message itself.

This patch converts aic79xx to use the midlayer-supplied tcq
functions.
We also set the queuedepth to '1' if tcq is disabled; the
aic79xx driver gets confused otherwise. Will set it back to
'2' once I figure out how to queue requests in the driver.

dual channel adapters
Introduce lpfc_reset_barrier() function for resets on dual channel adapters
Workaround for a hardware errata on dual channel asics. There is a
potential for the chip to lock up on a reset if a shared dma engine is in
use. The (ugly) work around requires a reset process which uses a mailbox
command to synchronize the independent channels prior to the reset to
avoid the issue. Unfortunately, the timing windows required to ensure this
workaround succeeds are very specific, meaning we can't release the cpu
during the barrier.

The patch
[SCSI] SCSI core kmalloc2kzalloc
Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc
to kzalloc, but then removes the clearing of the stack variable struct
packet_command. This, in turn leaves rubbish in the sense pointer
which the sr_do_ioctl() command then happily writes to ... oops.
Thanks to Mike Christie <michaelc@cs.wisc.edu> for spotting this.

Ok, so here is my first take at satisfying this request.
Be warned, that beyond compiling, and checking that the new module
doesn't immediately blow up, there hasn't yet been a lot of testing.
But this should allow you to comment on the changes, and move forward
with dropping scsi_request from the kernel code.

Protect NPL lists with host lock
Symptoms: lpfc_findnode_rpi and lpfc_findnode_did can be called
outside of the discovery thread context. We have to iterate
through the NPL lists under the host lock and all add/del
operations on those lists have to be done under host lock.

Fix deadlock in lpfc_fdmi_tmo_handler
lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock
held. lpfc_fdmi_cmd assumes the host_lock is released as it calls functions
that acquire the host_lock. lpfc_fdmi_tmo_handler acquired the host_lock to
protect access to work_hba_events. This was already checked in the worker
thread so we can remove that code completely and remove access to the
host_lock.

pci_read_config_byte() macro
PCI hrd_type should be obtained with pci_read_config_byte() macro
Driver keys off of this field to report the proper adapter type.
The pci subsystem explicitly clears the multiport bit in the copy of
the field given the driver. Thus, to properly name the card, obtain it
from config space.

aic94xx doesn't have a use for the bay or enclosure identifiers.
