Softint changes

[<rjs%fdy2.demon.co.uk@localhost>]

Could someone describe what is needed to get the rest of the powerpc
ports to build and work after the recent softint changes.

For NetBSD/ibmnws I can get a kernel to build by removing the include
of cpu.h from arch/ibmnws/include/intr.h but it crashes on startup
with this:

Starting syslogd.
