The variable bm_int_st is assigned a value but it is never read. The
variable and the assignment are redundant and can be removed.

The BusLogic driver has build errors on ia64 due to a name collision (in
the #included FlashPoint.c file). Rename the struct field in struct
sccb_mgr_info from si_flags to si_mflags (manager flags) to mend the build.
This is the first problem. There are 50+ others after this one:

The check on MAX_SCSI_TAR should be >= instead of > or we could go past the
end of the array.
Joe Eykholt aslo correctly points out that the check on MAX_LUN should be
>= as well. That matches with how it is used in the rest of the file.

We've verified that there are 64 bit and endianness problems in the
flashpoint driver. Reverse the logic of CONFIG_OMIT_FLASHPOINT (make
it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't
appear for any other architectures. Long term, if someone chooses,
they could make FlashPoint 64 bit compliant (it looks like its a
question of fixing up the sizes in some of the packed descriptors)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
