Change the PS3 irq allocation routines to take an argument indicating which
cpu (processor thread) the interrupt should be serviced on.
The current system configuration favors device interrupts that are serviced
on cpu0, so that is used as the default.

Various fixes for the PS3 repository code:
- Sync signatures of function prototypes and implementations (enum vs.
unsigned int)
- Correct references to `regions' as `registers':
o Correct enum ps3_region_type as enum ps3_reg_type,
o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*,
o Correct ps3_repository_find_region() as ps3_repository_find_reg().
- Correct function name in pr_debug() call
- Minor error condition improvements.

It appears that EEH is improperly enabled for some Power4 systems.
On these systems, the ibm,set-eeh-option returns a value of success
even when EEH is not supported on the given node. Thus, an explicit
check for support is required.
During boot, on power4, without this patch, one sees messages
similar to:
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2
etc.
The patch makes these go away.
Without this patch, EEH recovery does seem to work correctly for
at least some devices (I tested ethernet e1000), but fails to
recover others (the Emulex LightPulse LPFC, most notably).
Off the top of my head, I don't remember why some devices are
affected, but not others.
The PAPR indicates that the correct way to test for EEH is as
done in this patch; its not clear to me if this was in the PAPR
all along, or recently added; if it was there all along, its not
clear to me why this hadn't been fixed long ago. I suspect only
certain firmware levels are affected.

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.

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.

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.
