Now instead of having a ppc_md function, we just have a variable
which says whether to do the i8259 irq canonicalization or not,
and set that variable on the platforms that need that.  It looks
to me that radstone_ppc7d was trying to use irq canonicalization
for something else in a broken kind of way - it will need to be
fixed properly.

At the moment we don't have a merged arch/powerpc/boot, so we build the
boot images in arch/ppc/boot and arch/ppc64/boot.  Unfortunately the
makefile targets are different in those two directories, so this makes
a change to accommodate both for the moment.

This is a bunch of mostly small fixes that are needed to get
ARCH=powerpc to compile for 64-bit.  This adds setup_64.c from

Since lparmap.s gets included in arch/powerpc/kernel/head_64.S,

Although both ppc32 and ppc64 have a reloc_offset function, the ppc64
one produced the opposite sign to the ppc32 one.  This standardizes
on the ppc32 sign and fixes the merged 64-bit code to account for that.

The system call table has been consolidated into systbl.S.  We have
separate 32-bit and 64-bit versions of entry.S and misc.S since the
code is mostly sufficiently different to be not worth merging.
There are some common bits that will be extracted in future.

This adds register definitions from the ppc64 processor.h to reg.h,

This changes symbols like HID0, SPRG3, SRR0, SRR1 etc. that refer to
special purpose registers to SPRN_HID0, SPRN_SPRG3, etc.  Using the
SPRN_ symbols clutters the namespace less, and the forthcoming merge
of asm/processor.h and asm/reg.h is going to remove the non-SPRN_
versions.
