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):
   text    data     bss     dec     hex filename
 310865   49922    1204  361991   58607 linux-2.6.23.t/drivers/scsi/aic7xxx/built-in.o
 221987    2754    1204  225945   37299 linux-2.6.23-aic-3-addconst.t/drivers/scsi/aic7xxx/built-in.o

With debugging off:
   text    data     bss     dec     hex filename
 298896   42754    1172  342822   53b26 linux-2.6.23.tt/drivers/scsi/aic7xxx/built-in.o
 216068    2754    1172  219994   35b5a linux-2.6.23-aic-3-addconst.tt/drivers/scsi/aic7xxx/built-in.o

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.
