We sometimes forgot to check whether the exclusive store succeeded.
Ensure that we always check. Also ensure that we always use the
out of line versions, since the inline versions are not SMP safe.

If we found that the bit was already in the desired state, we
would skip performing the operation, and write random data back.

Patch from Alexander Schulz
This patch brings a new default config file for the shark and
fixes a compilation issue with io addressing and a runtime
problem with the serial ports, where I corrected a wrong
regshift value.
These are all shark specific files so I hope it is ok to
put them in one patch.

Patch from Nicolas Pitre
Those are big, slow and generally not recommended for kernel code.
They are even not present on i386. So it should be concluded that
one could as well get away with do_div() alone.

Convert ARM bitop assembly to a macro. All bitops follow the same
format, so it's silly duplicating the code when only one or two
instructions are different.

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!
