Subject: [PATCH 0/3] aic7xxx: debloat

Hi Hannes,

aic7xxx still contains ~30kb of dead code if pretty printing of registers
is requested. These patches deal with it.

I did not get any feedback from you whether the approach of adding
"dont_generate_debug_code" marker would be acceptable despite
asking twice. I decided that it's a "Yes".

The patches are compile tested on linux-2.6.26-rc8 and apply cleanly to
current scsi-misc.

Size differences:
