1f8404ea5f sh: Disable 4KSTACKS on nommu.
4k stacks on nommu ends up blowing up with all sorts of interesting
slab corruption. Disable this by default unless BROKEN is also
enabled.

a8f67f4b4d sh: Add SH7263 CPU support.
This adds support for the SH7263 (SH-2A) CPU.

This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.

No visibly nasty surprises, yet..

110ed28246 sh: Decouple 4k and soft/hardirq stacks.
While using separate IRQ stacks can cut down on stack consumption,
many users can also use 4k stacks directly without the additional
need of separate stacks for soft and hardirqs.

With this split, we support the same rationale for 4KSTACKS as
m68knommu, with the IRQSTACKS abstraction as per ppc64.

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.

fc31b80957 sh: Rip out broken kgdb thread support.
The kgdb thread support is woefully out of date (it predates
the pidhash), and needs a complete rewrite before it's useful
again. Just rip it out entirely.

Updating the unified kgdb stub is a more worthwhile endeavour
for anyone that happens to be interested in this, at present
it's just limping along.

6fc21b82ef sh: More flexible + SH7780 earlyprintk SCIF support.
This makes the early printk support somewhat more flexible,
moving the port definition to a config option, and making the
port initialization configurable for sh-ipl+g users.

At the same time, this allows us to trivially wire up the
SH7780 SCIF0, so that's thrown in too more or less for free.

cad8244840 [PATCH] sh: Move CPU subtype configuration to its own Kconfig
Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat.

Given that, this moves all of that in to its own arch/sh/mm/Kconfig.  Things
like cache configuration are also moved to this new location.

This also adds support for strict CPU tuning on newer cores, which requires
the addition of as-option.

1da177e4c3 Linux-2.6.12-rc2
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!
