This patch kills the whole embedded System.map mecanism and the
bootloader-passed System.map that was used to provide symbol resolution in
xmon. Instead, xmon now uses kallsyms like ppc64 does.
No hurry getting that in Linus tree, let it be tested in -mm for a while
first and make sure it doesn't break various embedded configs.

Made the number of TLB CAM entries private and converted the board
consumers to use num_tlbcam_entries which is setup at boot time from
configuration registers. This way the only consumers of the #define
NUM_TLBCAMS are the arrays used to manage the TLB.

Remove PG_highmem, to save a page flag. Use is_highmem() instead. It'll
generate a little more code, but we don't use PageHigheMem() in many places.

On ppc32, the platform code can supply a "progress" function that is
used to show progress through the boot. These functions are usually
in an init section and so can't be called after the init pages are
freed. Now that the cpu bringup code can be called after the system
is booted (for hotplug cpu) we can get the situation where the
progress function can be called after boot. The simple fix is to set
the progress function pointer to NULL when the init pages are freed,
and that is what this patch does (note that all callers already check
whether the function pointer is NULL before trying to call it).

CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used in
the code base. Fixed up the usage such that CONFIG_PTE_64BIT is used when we
have a 64-bit PTE regardless of physical address width. CONFIG_PHYS_64BIT is
used if the physical address width is larger than 32-bits, regardless of PTE
size.
These changes required a few sub-arch specific ifdef's to be fixed and the
introduction of a physical address format string.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
