A few minor things were broken here. fix and var screeninfo should have
been __devinitdata, board_list[] gets renamed to board_driver[] so the
modpost matching does the right thing, and we properly discard some of
the unused exit sections.

These should be returning a uint32_t, whereas they were erroneously
returning a u64 before. As the register sizes are 32-bits, this doesn't
really make a lot of sense.

With the TMU register definitions being renamed on SH-4, SH-3 ended up

SH is able to support a complete futex implementation on UP by way
of gUSA. However, IRQ toggling must be done for the old CPUs that
don't have movli.l/movco.l (LL/SC) instructions. Provide a default
implementation that does this, so it's possible to optimize for
newer CPUs.
Follows the same scheme as the current asm-sh/atomic-*.h headers.

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.
One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.

The shared intc2 code currently contains cpu-specific #ifdefs.
This is a tad unclean and it prevents us from using the shared code
to drive board-specific irqs on the se7780 board.
This patch reworks the intc2 code by moving the base addresses of
the intc2 registers into struct intc2_desc. This new structure also
contains the name of the controller in struct irq_chip. The idea
behind putting struct irq_chip in there is that we can use offsetof()
to locate the base addresses in the irq_chip callbacks.

SH-2 can presently get in to some pretty bogus states, so
we tidy up the dependencies a bit and get it all building
again.
This gets us a bit closer to a functional allyesconfig
and allmodconfig, though there are still a few things to
fix up.

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.

Slub currently defaults to 8-byte alignment for the kmalloc
and slab minalign values, where 4 will suffice. In the slab
case BYTES_PER_WORD == 4 already, so defining the minalign
values outright doesn't cause any regressions there either.

Now that select no longer works for selecting the "closest" CPU,

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.
