Including support for non-coherent cache, some mm-related things +
relevant field in Kconfig and Makefiles. Also included rheap.o compilation
if 8xx is defined.
Non-coherent mapping were refined and renamed according to Cristoph
Hellwig. Orphaned functions were cleaned up.
[Also removed arch/ppc/kernel/dma-mapping.c, because otherwise
compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up
with two copies of __dma_alloc_coherent etc.

This makes cpm uart able to work using OF-passed parameters

It's useful to have access to struct ipic handle that just got created
in ipic_init().
For example, if we want to setup an external IRQ with out
a device node we need access ipic->irqhost to create the virtual to HW
IRQ mapping and to set the IRQ sense. With this we can mimic the old
sense array concept that existed in arch/ppc.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler). Therefor, we can't call
ioremap in the reset function. Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.
However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called. If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.

- Drivers will not rely on the PCI config space value, as they've
already been conditioned to rely on the irq field in "struct pci_dev".
- The virq value may not be < 256 as it has been remapped.
- The PCI config space should reflect the hardware configuration, which
is not being changed. We are only creating a virtual irq mapping that
exists in the kernel only. One would never expect the PCI hardware to
generate the "virq" interrupt.

I often test new versions of glibc by doing:
LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>
One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:
00100000-00103000 r-xp 00100000 00:00 0 [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0 [heap]

ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack]
One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:
00100000-00103000 r-xp 00100000 00:00 0 [vdso]

The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.
The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id. The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.
The fix is to be careful and actually do the GDT setups correctly.

Both "=r" and "=g" breaks my build on i386:
$ make
CC [M] drivers/kvm/vmx.o
{standard input}: Assembler messages:
{standard input}:3318: Error: bad register name `%sil'
make[1]: *** [drivers/kvm/vmx.o] Error 1
make: *** [_module_drivers/kvm] Error 2
The reason is that setbe requires an 8-bit register but "=r" does not
constrain the target register to be one that has an 8-bit version on
i386.
According to
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10153
the correct constraint is "=q".
