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.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names

	make all the versions if die() have the same

Mikey and I were testing kexec and hit a lockup.  It turns out gcc 4.0
optimises the kexec_prepare_cpus loop so we avoid reloading paca.hw_cpu_id.

Merged cputable.h between ppc32 and ppc64.  In doing this removed support
for the BEGIN_FTR_SECTION/END_FTR_SECTION macros in C code since they
dont compile correctly.  C code should use cpu_has_feature().  This is
based on Arnd Bergmann's initial patch.

The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5.  It drives things like fans, i2c busses, real time
clock, etc...

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes.

It looks like we have been calling the non LPAR iommu_dev_setup on LPAR
machines for a while. The recent iommu fix caused that code path to
fail.

It looks like we just need to hook up the devices iommu_table to the
parents one, so do that instead of calling iommu_dev_setup_pSeries and
crossing the streams.

reg propery, "linux,boot-cpu", and timebase/clock frequency.

With those properties in place we can remove:

- setup_iSeries_cache_sizes()
- code in iSeries_setup_arch() to calculate timebase etc.
- iSeries_calibrate_decr()
- smp_iSeries_numProcs() and simplify smp_iSeries_probe()

- define iseries_probe()
- call build_iSeries_Memory_Map() earlier
- return __pa() of the flat device tree from iSeries_early_setup()

- add iseries_md to machdep_calls
- build prom.o for iSeries
