It's very grep'able. > In some sense interrupts are the simpler case. > > Especially when comparing with other architectures which have > special instructions for syscall entry. powerpc does have a special instruction for syscall, and it causes a system call interrupt. I'm not sure about other architectures, but for powerpc its more sensible to call it interrupt.c than syscall.c. Thanks, Nick
