The ancient ppcdebug/PPCDBG mechanism is now only used in two places.
First, in the hash setup code, one of the bits allows the size of the
hash table to be reduced by a factor of 8 - which would be better
accomplished with a command line option for that purpose.  The other
was a bunch of bus walking related messages in the iSeries code, which
would seem to be insufficient reason to keep the mechanism.

This patch removes the last traces of this mechanism.

Built and booted on iSeries and pSeries POWER5 LPAR (ARCH=powerpc).

This also moves setup_cpu_maps to setup-common.c (calling it

register_vpa() doesn't actually do a VPA register call it just uses the flags
you pass it, so rename it to vpa_call() to be clearer.

We can then define register_vpa() and unregister_vpa() which are both simple
wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon)

We can then cleanup vpa_init(), and because vpa_init() is only called from
platforms/pseries we remove the definition in asm-ppc64/smp.h.

Currently there is no Kconfig symbol to indicate that we want nvram
support on 64-bit kernels; it's assumed we always want it, so make
the powermac setup code always initialize the pmac nvram code if
64-bit.

The extraction of PCI stuff from struct device_node left some false
assumptions in notifier code.  As a result, dynamic add crashes when
non-PCI nodes are added.  This patch fixes these assumptions.

This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since
cell wants them as well as pseries (and chrp can use rtas-proc.c too,
at least in principle).  rtas_fw.c is gone, with its bits moved into
rtas_flash.c and rtas.c.

These days, the NACA only exists on iSeries.  Therefore, this patch
moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries.
There was one file including naca.h outside of platforms/iseries -
arch/ppc64/kernel/udbg_scc.c.  However, that's obviously a hangover
from older days.  The include is not necessary, so this patch simply
removes it.

Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

We were getting powerbook sleep code included, and giving compile
errors, with CONFIG_PM=y on a 64-bit build.  This excludes that code
so the kernel will compile.  One day BenH will implement on sleep on

The nvram driver imported from the ppc code uses call_rtas, but
rtas_call is the name we are using in merged code (since ppc64 used
that name, and it uses far more RTAS calls than ppc32).

By parsing the command line earlier, we can add the mem= value to the
flattened device tree and let the generic code sort out the memory limit
for us.
Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au>

We had a static memory_limit in prom.c, and then another one defined
in setup_64.c and used in numa.c, which resulted in the kernel crashing
when mem=xxx was given on the command line.  This puts the declaration
in system.h and the definition in mem.c.  This also moves the
definition of tce_alloc_start/end out of setup_64.c.

This patch moves the XICS interrupt controller code into the
platforms/pseries directory, since it only appears on pSeries
machines.  If it ever appears on some other machine we can move it to
sysdev, although xics.c itself will need a bunch of changes in that
case to remove pSeries specific assumptions.
