This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.
This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

Add explicit disabling of 440GP IRQ compatibility mode when configuring
440GX interrupt controller. This helps when board firmware for some reason
uses this compatibility mode and leaves it enabled. It breaks 440GX
interrupt code because it assumes native 440GX IRQ mode. People seems to
be continuously bitten by this.

This patch adds interrupt acknowledge to the PPC4xx PIC enable_irq
implementation for level-sensitive IRQ sources. This helps in cases when
enable/disable_irq is used in interrupt handlers for hardware, which
requires IRQ acknowledge to be issued from non-interrupt context (e.g.
when actual ACK in device needs an I2C transaction). For such strange
hardware, interrupt handler disables IRQ and defers actual ACK to some
other context. When this happens, IRQ is enabled again. For
level-sensitive sources we get spurious triggering right after IRQ is
enabled. This patch fixes this.
Suggested by Tolunay Orkun <listmember@orkun.us>.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
