dc78e8a39c Add some conditional code to handle kernel versions less that 2.6.25 that 
can send a request as a non scatterlist. If we get one, we create a single
element scatterlist and hand that on to SCST. 

This costs some extra space in the structure I use to keep track of requests
and the done function, but only on those versions for which it is possible.
For real kernels it is scatterlists all the way down young man.

d1470f9526 Some time ago it became clear that some SCST users are using kernel 2.6.23. So 
it makes sense to run the nightly build also for kernel 2.6.23. But doing so
is only possible with the attached two files present in the SCST tree.
Except for the kernel version these patches are identical to the corresponding
patches for the 2.6.24 kernel.

8187f28719 Make scst_local compile cleanly on a range of versions of Linux. I have tested 
2.6.24, 2.6.25.4, 2.6.27.x and 2.6.29. I have also tested under 2.6.18 on a
CentOS 5.3 system. 

There might still be problems with some 2.6.18 systems, and I will commit more
changes as the need arises.

I have only tested that scst_local builds and loads with these changes. I have
not tested any devices as yet.

7519550fcb Moved scst_register() call from srpt_detect() to srpt_add_one(). Added 
call to scst_unregister() in srpt_remove_one(). Result:
- The kernel oops triggered by loading the ib_srpt kernel module before
  the InfiniBand subnet manager became active is now fixed.
- It is now possible to log in via the SRP protocol through HCA's that
  became active after the ib_srpt kernel module finished module
  initialization.

106acdb7d6 - Switched to a more traditional error handling style with regard to MAD

  handler registration fails.
- Fixed bug in srpt_refresh_port(): this function now returns a negative
  value instead of zero when MAD registration fails.
