Subject: [PATCH] debloat aic7xxx and aic79xx drivers by deinlining
Hi,
Attached patch deinlines and moves big functions from .h to .c files
in drivers/scsi/aic7xxx/*. I also had to add prototypes for ahc_lookup_scb
and ahd_lookup_scb to .h files.
No other code changes made.
Compile-tested on i386 and x86-64.
Total .text size reduction: ~60k in 64 bits, ~90k in 32 bits.
Per-object-file and whole-module size difference:
for x86-64:
