- The stuff in arch/ppc/boot/mvme2100 can go.

Figured that out today, too. It won't compile anyway. Thanks.

>- The open_pic.c change shouldn't be needed either.
Maybe the CONFIG_EPIC_SERIAL_MODE should be set, shouldn't it? Will add
it tomorrow. Should I add that cascade hookup stuff even if there is no
cascaded 8259?

There is one problem - in the LoPEC manual all interrupts are documented
- even if marked unused (I refer to polarity and level/edge). In the
MVME2100 information about that interrupts is N/A. So should I leave
those to 0 still in the initsenses struct?

Thanks for the help,
