Hi,
Following patches debloat drivers/scsi/aic7xxx/*.
I also had to add prototypes for ahc_lookup_scb
and ahd_lookup_scb to .h files.
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:
Build with debugging on (CONFIG_AIC7XXX_DEBUG_ENABLE=y):

With debugging off:

make namespacecheck goes from 400+ functions to:
drivers/scsi/aic7xxx/aic79xx_core.o
ahd_inq
ahd_inw
ahd_outq
ahd_outw
drivers/scsi/aic7xxx/aic79xx_osm.o
ahd_insb
drivers/scsi/aic7xxx/aic7xxx_core.o
ahc_inq
ahc_outq
drivers/scsi/aic7xxx/aic7xxx_osm.o
ahc_insb
None of these patches touch any logic, code changes are pretty minimal.
Compile tested and applies cleanly to 2.6.23.
I don't have this hardware anymore and cannot run test these patches.
Please apply.
