This patch works around an issue with WD drives (and possibly others)
over SiL PATA->SATA Bridges on SATA controllers locking up with
transfers > 200 sectors.

BCM5785 (HT1000) is a new southbridge from Serverworks/Broadcom that
incorporates 4 SATA ports in a single PCIX function. Functionally these
ports are similar to that in older devices like the Apple K2 and the
Frodo4/8. This patch adds support for the new PCI device ID along with a
blurb on what the various device IDs mean. Additionally in all devices
based on this SATA controller, the SATA ports appear as a single PCI
function. This is true for older Frodo8 devices as well. Hence the init
function should init all the ports present in the detected controller
(which could be 4 or 8).

The fixes for sparse warnings mixed in with the fixups for
the raw_srb handler resulted in a bug that showed up in the 32 bit
environments when trying to issue calls directly to the physical devices
that are part of the arrays (ioctl scsi passthrough).
Received from Mark Salyzyn at adaptec.
Applied comment from Christoph to remove cpu_to_le32(0)
Applied Mark S fix of missing memcpy.
It applies to the scsi-misc-2.6 git tree.

Drivers need not implement a hook that returns FAILED, and does nothing
else, since the SCSI midlayer code will do that for us.

There are several extra things that have to be considered when running
Domain Validation on a u320 target (notably how you fall back).
Hopefully this should help us when someone adds this transport class to
aic79xx.
I've tested this on the lsi1030, so I know it works correctly up to
u320.

A problem exists todayin the sg driver that if an SG_IO request is
outstanding to a device when it is removed from the system. The
system may oops if that command completes later in time.
1. sg_remove gets called
2. sg_remove calls sg_finish_req_req on all pending requests
This removes the Sg_request's from the headrp list in the Sg_fd
3. The sleeping SG_IO ioctl is woken. It does nothing and returns.
4. The caller closes the fd, which invokes sg_release
5. sg_release calls sg_remove_sfp. It finds no outstanding commands
since the headrp list is empty, so it calls __sg_remove_sfp,
which frees the sfp.
6. Now when sg_cmd_done gets called, sg uses upper_private_data in
the Scsi_Request, which should point to the srp, which has been
freed, so it points to freed memory.
7. sg then dereferences the srp pointer to get the sfp, and we oops.
The fix is to NULL out the upper_private_data field in this path,
which sg_cmd_done already checks for, which will prevent the oops
from occurring.

Since the aic driver is now taught to speak in terms of the generic
linux devices, we can now also dispense with the transport class get
routines (since we update the parameters when the driver sees they
change) and also plumb it into the spi transport transfer agreement
reporting infrastructure.

a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h
b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off
c) relevant places in midlayer and sd.c taught to accept TYPE_RBC
d) sd.c::sd_read_cache_type() looks into page 6 when dealing with
TYPE_RBC - these guys have writeback cache flag there and are not guaranteed
to have page 8 at all.
e) sd_read_cache_type() got an extra sanity check - it checks that
it got the page it asked for before using its contents. And screams if
mismatch had happened. Rationale: there are broken devices out there that
are "helpful" enough to go for "I don't have a page you've asked for, here,
have another one". For example, PL3507 had been caught doing just that...
f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead
of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions
in there are gone now.
Incidentally, I wonder if USB storage devices that have no
mode page 8 are simply RBC ones. I haven't touched that, but it might
be interesting to check...

New code from the Adaptec driver. Performance enhancement for newer
adapters. I hope that this isn't too big for a single patch. I believe
that other than the few small cleanups mentioned, that the changes are
all related.
- Added Variable FIB size negotiation for new adapters.
- Added support to maximize scatter gather tables and thus permit
requests larger than 64KB/each.
- Limit Scatter Gather to 34 elements for ROMB platforms.
- aac_printf is only enabled with AAC_QUIRK_34SG
- Large FIB ioctl support
- some minor cleanup
Passes sparse check.
I have tested it on x86 and ppc64 machines.

Save and restore the scmd->result, so that timed out commands do not
return the result of the TEST UNIT READY or the start/stop commands. Code
is already in place to save and restore the result for the request sense
case.
The previous version of this patch erroneously removed the "if" check,
instead add a comment as to why the "if" is needed.

scsi_queue_insert() has four callers. Three callers call with
timer disabled and one (the second invocation in
scsi_dispatch_cmd()) calls with timer activated.
scsi_queue_insert() used to always call scsi_delete_timer()
and ignore the return value. This results in race with timer
expiration. Remove scsi_delete_timer() call from
scsi_queue_insert() and make the caller delete timer and check
the return value.
