How about splitting the files on a per-case bases then? There are at least
95 files that would need to be duplicated (again) to make ppc independent
from powerpc, and most of these files are about userland interfaces where
duplication makes no sense at all.
Some files in there (irq.h, ipic.h, dcr.h, i8259.h) already have large
parts hidden in #ifdef CONFIG_PPC_MERGE, so I guess for those it may
actually be interesting to split them in two again.
