support for NCR voyager (3/4/5xxx series)

This patch adds SMP (and UP) support for voyager which is an (up to 32 way) SMP microchannel non-PC architecture.

There's basically nothing different from the 2.5.15 one except for merge fixes and changes to the tlb and process init code.

The patch is in two parts: The i386 sub-architecture split is separated from the addition of the voyager components

(The split diff is pretty huge because it's actually moving files about). You must apply the split diff before applying the voyager one.

These two patches are also available as separate bitkeeper trees (the voyager tree contains the arch-split tree):
