While we're at it, already existing aicXXXX driver continues to be
insanely large due to excessive inlining of I/O routines:
# x86_64-pc-linux-gnu-size aic7xxx.o
text data bss dec hex filename
118978 22673 568 142219 22b8b aic7xxx.o
This is not even helping performance one iota.
Call overhead for these routines pales in comparison
to I/O instruction stalls, which is in turn pales in comparison to
disk seek delays.
Please do something with it.
