5d2685d0b3 sh: Conditionalize the code dumper on CONFIG_DUMP_CODE.
We don't really want this enabled by default, but it is still quite
useful for debugging. So, make it conditional and leave it off by
default.

740a3e677b sh: Enable skipping of bss on debug platforms for sh32 also.
This enables the same functionality that sh64 has for sh32. When running
on simulated hardware or via remote memory via the debug interface,
memory is gauranteed to be zero on boot already, and skipping the zeroing
of BSS has measurable boot time benefits.

ab6e570ba3 sh: Generic kgdb stub support.
This migrates from the old bitrotted kgdb stub implementation and moves
to the generic stub. In the process support for SH-2/SH-2A is also added,
which the old stub never provided.

a99d6fde69 sh: Convert sh64 /proc/asids to debugfs and generic sh.
This converts the sh64 /proc/asids entry to debugfs and enables it for
all SH parts that have debugfs enabled.

On MMU systems this can be used to determine which processes are using
which ASIDs which in turn can be used for finer grained cache tag
analysis.

b817f7e020 sh: Disable 4kB stacks when using PAGE_SIZE_64KB.
This combination triggers a divide by zero in kernel/fork.c when
calculating the initial max_threads value:

	max_threads = mempages / (8 * THREAD_SIZE / PAGE_SIZE);

Simply disable 4K stacks on 64kB PAGE_SIZE to work around this,
as it's not a terribly useful combination to begin with.

This adds support for the SH7263 (SH-2A) CPU.

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.

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The kgdb thread support is woefully out of date (it predates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!
