This was added during 2.5.x, but was never moved along. This
can easily be resurrected if someone has one they wish to work
with, but it's not worth keeping around in its current form.

Currently cpu_to_node() is always 0 in the UP case, though
we do want to have the CPU association linked in under sysfs
even in the cases where we're only on a single CPU.
Fix this up, so we have the cpu0 link on all of the available
nodes that don't already have a CPU link of their own.

This adds the URAM block on SH7722 as a separate node.
Sparsemem is required for this, or it can simply be disabled
by explicitly selecting a flatmem model.

We have to call in to sparse_memory_present_with_active_regions()
earlier in order for sparsemem to be happy. This was being called
too late, and was causing troubles with the platforms that needed
to enable sparsemem.

This implements basic sparsemem support for SH. Presently this only
uses static sparsemem, and we still permit explicit selection of
flatmem. Those boards that want sparsemem can select it as usual.

.machvec.init can be misaligned with the recent machvec changes,
forcibly align it on the boundary that it expects, as before.

Now that select no longer works for selecting the "closest" CPU,
we have to explicitly reference the precise sub-type in the few
places where it actually matters (presently only setup code and
some legacy sh-sci cruft).

This kills off the BareCPU board as a "special" machvec, rather,
we leave this as a default for when no other vector is available,
or when we want to use it in combination with other vectors for
testing with generic ops. As sh_mv is copied out anyways (or
overloaded when an alternate vector is explicitly selected), this
doesn't consume any additional memory.
The generic machvec can be forcibly selected with sh_mv=generic,
or by not having any other boards enabled.

We now throw all of the machvecs in to .machvec.init and either
select one on the command line, or copy out the first (and
usually only) one to sh_mv. The rest are freed as usual.
This gets rid of all of the silly sh_mv aliasing and makes the
selection explicit rather than link-order dependent.

This fixes up much of the machvec handling, allowing for it to be
overloaded on boot. Making practical use of this still requires
some Kconfig munging, however.

This adds in some more __user annotations. These weren't being
handled properly in some of the __get_user and __put_user paths,
so tidy those up.

Split out the CPU topology initialization to a separate file,
and switch it to a percpu type, rather than an NR_CPUS array.
At the same time, switch to only registering present CPUs,
rather than using the possible CPU map.

With the SH7722 changes, ->set_rate() also takes an algo_id,
SH4-202 was overlooked when this change went in.

If CONFIG_KGDB_NMI is disabled, we're left with a stray in_nmi
reference that can't be resolved. Move the symbol under the ifdef,
too.

Several errors were spotted during building for custom config (SMP
included). Although SMP still does not compile (no ipi and
__smp_call_function) and does not work, this looks a bit cleaner.
Some other errors obtained via gcc-4.1.0 build.
