e6b6e3ffb9 [POWERPC] Remove APUS support from arch/ppc
Current status of APUS:
- arch/powerpc/: removed in 2.6.23
- arch/ppc/: marked BROKEN since 2 years

This therefore removes the remaining parts of APUS support from
arch/ppc, include/asm-ppc, arch/powerpc and include/asm-powerpc.

0a26b1364f ppc: Remove CHRP, POWER3 and POWER4 support from arch/ppc
32-bit CHRP machines are now supported only in arch/powerpc, as are
all 64-bit PowerPC processors.  This means that we don't use
Open Firmware on any platform in arch/ppc any more.

This makes PReP support a single-platform option like every other
platform support option in arch/ppc now, thus CONFIG_PPC_MULTIPLATFORM
is gone from arch/ppc.  CONFIG_PPC_PREP is the option that selects
PReP support and is generally what has replaced
CONFIG_PPC_MULTIPLATFORM within arch/ppc.

_machine is all but dead now, being #defined to 0.

Updated Makefiles, comments and Kconfig options generally to reflect
these changes.

f1434a4854 [PATCH] powerpc: fix altivec_unavailable_exception Oopses
altivec_unavailable_exception is called without setting r3... it looks like
the r3 that actually gets passed in as struct pt_regs *regs is the
undisturbed value of r3 at the time the altivec instruction was encountered.
The user actually gets to choose the pt_regs printed in the Oops!

This fixes the oops by passing the correct pt_regs pointer to
altivec_unavailable_exception.

fd582ec88e ppc: Various minor compile fixes
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.

dc1c1ca3dc powerpc: merge idle_power4.S and trapc.s
Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype

400d221274 [PATCH] ppc32: make cur_cpu_spec a single pointer instead of an array
Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs.
Additionally, made call_setup_cpu check to see if the cpu_setup pointer
is NULL or not before calling the function.  This lets remove the dummy
cpu_setup calls that just return.

5f7c690728 [PATCH] powerpc: Merged ppc_asm.h
Merged ppc_asm.h between ppc32 & ppc64.  The majority of the file is
common between the two architectures excluding how a single GPR is
saved/restored and which GPRs are non-volatile.

Additionally, moved the ASM_CONST macro used on ppc64 into ppc_asm.h.

31139971b3 [PATCH] ppc32: support hotplug cpu on powermacs
This allows cpus to be off-lined on 32-bit SMP powermacs.  When a cpu
is off-lined, it is put into sleep mode with interrupts disabled.  It
can be on-lined again by asserting its soft-reset pin, which is
connected to a GPIO pin.

With this I can off-line the second cpu in my dual G4 powermac, which
means that I can then suspend the machine (the suspend/resume code
refuses to suspend if more than one cpu is online, and making it cope
with multiple cpus is surprisingly messy).

443a848cd3 [PATCH] ppc32: refactor FPU exception handling
Moved common FPU exception handling code out of head.S so it can be used by
several of the sub-architectures that might of a full PowerPC FPU.

Also, uses new CONFIG_PPC_FPU define to fix alignment exception handling
for floating point load/store instructions to only occur if we have a
hardware FPU.

1da177e4c3 Linux-2.6.12-rc2
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!
