The same for board control.

Remove ugly all-over-the-code casts of ctl_addr to 9060 space.
Add an union to the cyclades_card structure, which contains
a pointer to both 9050 and 9060 spaces.

The 9050 space layout is unknown, so let it still as a void
__iomem pointer.

A number of standard posix types are used in exported headers, which
is not allowed if __STRICT_KERNEL_NAMES is defined. In order to
get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers
the default, we have to change them all to safe types.

There are also still some leftovers in reiserfs_fs.h, elfcore.h
and coda.h, but these files have not compiled in user space for
a long time.

This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t),
which we take care of separately.

At least on x86_64 the present cyclades.h is broken due to the wrong size
of uclong.  This affects, of course, both the kernel and the user-level
utilities.  The symptom is that cyzload refuses to load the firmware.  I
also managed to freeze the machine when unloading the module.

The patch below fixes this in an architecture-independent way.  I have
tested it with 2.6.19 and the driver works fine again with a Cyclades-Z on
an Athlon 64 X2.

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!
