357d59469c sh: Tidy up dependencies for SH-2 build.
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.

87e29cacb7 sh: Use L1_CACHE_BYTES for .data.cacheline_aligned.
Previously this was using a hardcoded 32, use L1_CACHE_BYTES for
cacheline alignment instead.

26ff6c11ef sh: page table alloc cleanups and page fault optimizations.
Cleanup of page table allocators, using generic folded PMD and PUD
helpers. TLB flushing operations are moved to a more sensible spot.

The page fault handler is also optimized slightly, we no longer waste
cycles on IRQ disabling for flushing of the page from the ITLB, since
we're already under CLI protection by the initial exception handler.

b638d0b921 sh: Optimized cache handling for SH-4/SH-4A caches.
This reworks some of the SH-4 cache handling code to more easily
accomodate newer-style caches (particularly for the > direct-mapped
case), as well as optimizing some of the old code.

1fd73c6b67 [PATCH] Kill L1_CACHE_SHIFT_MAX
Kill L1_CACHE_SHIFT from all arches.  Since L1_CACHE_SHIFT_MAX is not used
anymore with the introduction of INTERNODE_CACHE, kill L1_CACHE_SHIFT_MAX.

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!
