another signdness warning from gcc 4.1

drivers/scsi/osst.c:5154: warning: comparison of unsigned expression < 0 is always false

The problem is that blk is defined as unsigned, but all usages of it are
normal int cases.  osst_get_frame_position() and osst_get_sector() return ints
and can return negative values.  If blk stays an unsigned int, the error check
is useless.

When testing on a Unisys machine it was discovered that the megaraid driver
would not initialize as it was requesting irq 162 instead of irq 1442 it
was assigned.  The problem was the irq number had been truncated by being
stored in an unsigned char.

This patches fixes that problem and the driver now appears to work.

The ioctl interface appears fundamentally broken as it exports the irq
number to user space in an unsigned char.

have received a couple of reports of people hitting this one with
various tape configurations and the patch looks obviously correct.

This sg driver patch addresses the problem with larger
page sizes reported by Brian King in this post:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115867718623631&w=2
Some other related matters are also addressed. Some of these
prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are
set to inappropriate values.

The scatter_elem_sz has been tested up to 4 MB which should
make the largest data transfer with one SCSI command, 32 MB
less one block, achievable with a relatively small number
of elements in the scatter gather list.

ChangeLog:
    - add scatter_elem_sz boot time parameter and sysfs module
      parameter that is initialized to SG_SCATTER_SZ
    - the driver will then adjust scatter_elem_sz to be the
      max(given(scatter_elem_sz), PAGE_SIZE)
      It will also round it up, if necessary, to be a power
      of two
    - clean up sg.h header, correct bad urls and some statements
      that are no longer valid
    - make the def_reserved_size sysfs module attribute writable

This started as a PCI reference fixup but to do that I need to build it,
to build it I need to fix it and its full of 32bitisms and uglies.

It has been resurrected, I'm not sure if this is a thank you for the
work on the license stuff or punishment for some unknown misdeed however
8). I've also fixed a memory scribble in the init code.

One oddity - the changes from HZ * to constants are deliberate. Whoever
originally wrote the code (or cleaned it up) used HZ for a cycle timing
loop even though is not HZ related. I've put it back to the counts used
in the old days when the driver was most used.

Received from Mark Salyzyn:

Until the system is stabilized, I am suggesting the enclosed
modification to prevent the driver from tickling the panic. Once sysfs
and friends are stabilized, the patch may be backed out. We have yet to
evaluate if we really want to relinquish existing Scsi Devices in any
case, holding on to them as configuration of arrays comes and goes makes
some sense as well. As a result, we have opted to pull the lines rather
than comment them in legacy.

The only real difference between the rkt and rx platform modules is the
offset of the message registers. This patch recognizes this similarity
and simplifies the driver to reduce it's code footprint and to improve
maintainability by reducing the code duplication.

Visibly, the 'rkt.c' portion of this patch looks more complicated than
it really is. View it as retaining the rkt-only specifics of the
interface.

I am placing this functionality into an insmod parameter. Normally the physical
components are exported to sg, and are blocked from showing up in sd.

Note that the pass-through I/O path via the driver through the Firmware to the
physical disks is not an optimized path, the card is designed for Hardware
RAID, elevator sorting and caching. This should not be used as a means for
utilizing the aacraid based controllers as a generic scsi/SATA/SAS controller,
performance should suck by a few percentage points, any RAID meta-data on the
drives will confuse the controller about who owns the drives and there is a
high risk of destroying content in both directions. Unreliable and for
experimentation or strange controlled circumstances only.

For cards that don't support LVD, checking the SBLKCTL register to

  0170-0177 : libata
  01f0-01f7 : libata
