Hi Andrew,
Can you please take these patches into -mm?
I seem to be unable to push them through scsi people,
they silently drop them on the floor.
There patches significantly debloat drivers/scsi/aic7xxx/*.
1-debloat.patch
Deinlines and moves big functions from .h to .c files.
Adds prototypes for ahc_lookup_scb and ahd_lookup_scb to .h files.
2-addstatic.patch
Adds statics, #ifdefs out huge amount of unused code, adds consts
3-addconst.patch
Adds more consts
Driver code/data size reductions with and without debugging enabled
(aic0 is just an unmodified linux-2.6.25-rc6):

None of these patches touch any logic, code changes are pretty minimal.
Compile tested and applies cleanly to 2.6.25-rc6.
I don't have this hardware anymore and cannot run test these patches,
but other people reported success in the past:
