The failure to map user-space pages leads to scsi command leak. It can
happens mostly because of user-space daemon bugs (or OOM). This patch
makes tgt just notify a LLD of the failure with sense when
blk_rq_map_user() fails.

This patch simplify the way to notify LLDs of the command completion
and addresses the following sense buffer problems:

- can't handle both data and sense.
- forces user-space to use aligned sense buffer

tgt copies sense_data from userspace to cmnd->sense_buffer (if
necessary), maps user-space pages (if necessary) and then calls
host->transfer_response (host->transfer_data is removed).

scsi tgt breaks up a command into multple scatterlists
if we cannot fit all the data in one. This was because
the block rq helpers did not support large requests and
because we can get a command of any old size so it is
hard to preallocate pages for scatterlist large enough
(we cannot really preallocate pages with the bio map
user path). In 2.6.20, we added large request support to
the block layer helper, blk_rq_map_user. And at LSF,
we talked about increasing SCSI_MAX_PHYS_SEGMENTS for
scsi tgt if we want to support really really :) large
(greater than 256 * PAGE_SIZE in the worst mapping case)
requests.

The only target currently implemented does not even support
the multiple scatterlists stuff and only supports smaller
requests, so this patch just coverts scsi tgt to use
blk_rq_map_user.

SCSI code cannot operate properly unless we get an inquiry length of
36 or above (because of the way we parse vendor and product), so

The sequencer firmware file has both a string (currently showing
V17/10c6) and a number (currently set to 1.1).  It has become apparent
that Adaptec may issue sequencer firmware in the future which could be
incompatible with the current driver.  Therefore, the driver will be
tied to the particular major number of the firmware (i.e. the current
driver will load any 1.x firmware).  Additionally, the driver will print
out both the ascii string and the major number, so with this pach the
current firmware will print out

This patches fixes two bugs in the scsi target infrastructure's
user/kernel interface.

- It wrongly assumes that the ring buffer size of the interface (64KB)
is larger than or equal to the system page size. This patch sets the
ring buffer size to PAGE_SIZE if the system page size is larger.

- It uses PAGE_SIZE in the header file exported to userspace. This
patch removes it.

1) sgiwd93 used to switch off asynchronous mode on the wd33c93, discarding
   any "nosync"-requests from the commandline.
   But we need to allow "nosync"-requests for selected devices, for example
   the Pioneer DVD305S.
   (For the curious: this device accepts the SDTR from wd33c93 and success-
   fully sends inquiry data in sync mode, but after the data phase in the
   inquiry command does an unexpected disconnect, seemingly sending no
   "status" or "command complete". Forcing async transfers makes it work
   together flawlessly with the wd33c93. Of course, preferable would be, to
   implement wd33c93's "resume command" stuff, but that probably will not
   come soon.)

2) Maximize benefit from the preceding Fast SCSI patch for wd33c93 by passing
   the higher input-clock frequency explicitely. To be applied after the
   mentioned wd33c93 patch.
