Don't allow CONFIG_INFINIBAND_IPOIB_DEBUG to be disabled unless
CONFIG_EMBEDDED is selected.  We want users (and especially distros)
to have this turned on unless they really need to save space, because
by the time we want debugging output, it's usually too late to rebuild
a kernel.  The debugging output can be controlled at runtime via the
debug_level module parameter in sysfs.

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!
