This applies cleanly againt 2.5.59.  It gets rid of the ugly multi-line
C macros in entry.S and cleans up the declarations of the interrupt
handler functions.

Something in my previous patches was causing faulures with gcc-3.2.  I
suspect it was one of the functions using regparm(1) and asmlinkage
(which implies regparm(0)) at the same time.

Tested:
UP gcc-3.2
SMP gcc-3.2 and 2.95.4
