powerpc: Simplify and clean up the xmon terminal I/O
This factors out the common bits of arch/powerpc/xmon/start_*.c into
a new nonstdio.c, and removes some stuff that was supposed to make
xmon's I/O routines somewhat stdio-like but was never used.
It also makes the parsing of the xmon= command line option common,
so that ppc32 can now use xmon={off,on,early} also.

powerpc: Fix crash in early boot on some powermacs
Some powermac machines were crashing in the quiesce firmware call

notably my 1999 G3 powerbook does this. To avoid this, don't
close the OF stdin device on powermacs.

memmap_init_zone() sets page count to 1. Before 'freeing' the

[PATCH] ppc64: Fix the lazy icache/dcache code for non-RAM pages
For some stupid reason I can't explain (brown paper bag is at hand), I

coherency on POWER4 and later. That causes us to eventually try to
access non existing struct page when hashing in IO pages.

This seems to be done in other parts of the Kconfig file. Using those
as an example, this should keep the MAX_ORDER block size at 16MB.

- resource.c: pnp_register_mem_resource
Note that this patch #if 0's exactly one functions and removes no
functions. Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
code will use any of them, re-adding will be trivial.
Modular ISAPnP might be interesting in some cases, but this is more legacy
code. If someone would work on it to sort all the issues out (starting
with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.
