We need to check the address that pci_alloc_consistent() returns since
it might fail.
When pci_alloc_consistent() fails, some IOMMUs set the dma_handle
argument to zero. So we can't use fibptr->hw_fib_pa directly here.

A lot of 64bit machines with Adaptec 2200S and 2120S controllers don't

[SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID Controller 3/Di
but fail with tons of "aac_srb: aac_fib_send failed with status: 8195"
instead. This patch disables the quirk introduced in the change cited
above for those two controllers again.

aacraid updates the timeout in its slave configure routine if it is too
small. This now needs to update the request queue timeout in block.

Right now SCSI and others do their own command timeout handling.
Move those bits to the block layer.
Instead of having a timer per command, we try to be a bit more clever
and simply have one per-queue. This avoids the overhead of having to
tear down and setup a timer for each command, so it will result in a lot
less timer fiddling.

Seen:
kernel BUG at arch/i386/lib/usercopy.c:872
under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out
ioctl condition in the aacraid driver.
Adaptec's special ioctl scb passthrough needs to check the validity of
the individual scatter gather count fields to the maximum the adapter
supports. Doing so will have the side effect of preventing
copy_from_user() from bugging out while populating the dma buffers.
This is a hardening effort, issue was triggered by an errant version
of the management tools and thus the BUG should not be seen in the
field.

For firmware that supports the feature(s), add the ability to start or
stop an array using the associated SCSI commands, to automatically
manage the spin-up of an array on new I/O reporting back the
appropriate check conditions and actions in cooperation with the
normal timeout mechanisms and enable the blackout period management in
the Firmware associated with the background spin-down of the arrays
when the Firmware times out and deems the arrays as idle.

As JBOD devices (really just Simple Single Drive Volumes exported to
the SCSI channel) are managed, they fail to update correctly when the
driver triggers a SCSI scan. In addition, the ability to change
multiple arrays or JBODs at the same time was resulting in dropped
scans, set up a mechanism to issue a list of single target scans on a
single configuration change notification from the Firmware.
Performed some additional sundry cosmetic code style cleanups.

Fixed trivial conflict in include/linux/memory.h due to semaphore header
file change (made irrelevant by the change to mutex).
None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.
