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!

um: fix stub exe build with CONFIG_GCOV CONFIG_GCOV is special and only in UML since it builds the kernel with a "userspace" option. This is fine, but the stub is even more special and not really a full userspace process, so it then fails to link as reported. Remove the GCOV options from the stub build. For good measure, also remove the GPROF options, even though they don't seem to cause build failures now. To be able to do this, export the specific options (GCOV_OPT and GPROF_OPT) but rename them so there's less chance of any conflicts.
