RFC: [PATCH] Copy over headers from arch/powerpc to arch/ppc to decouple them

Tue Aug 28 00:49:04 EST 2007
Move over includes files that have CONFIG_PPC_MERGE in them to decouple
to interdepencies between ARCH=powerpc & ARCH=ppc.
Duplicate the following headers in both locations and remove CONFIG_PPC_MERGE:
<asm/dcr.h>
<asm/i8259.h>
<asm/ipic.h>
<asm/irq.h>
---
Not sure what people think about this since removing include asm-powerpc
from ARCH=ppc builds will require a bunch of other copies beyond these
which had a CONFIG_PPC_MERGE in them.

Removed new file creation (since they duplicate the include/asm-powerpc
version, with CONFIG_PPC_MERGE folded out).
