Yes, I've seen these but since Al's patches are not in mainline, I don't
want to add additional dependencies to the arm64 patches (currently
based on 3.6-rc4). Once they get into mainline, I'll add a patch that
converts arm64 to the generic functions above.

For kernel_execve(), I think I can simplify it further and not rely on
Al's patches (similar to other architectures doing an SVC from kernel):

Hmm, I thought one of the reasons for Al to do his series was to discourage
people from doing syscalls from kernel space, but I may be misremembering
things. Al?

If that was the aim, I'm happy to change the code similar to the
arch/arm one. But as I said I would wait until Al's patches get into
mainline.

Ok. Another point: I wouldn't be too worried about dependencies for new
code, because it's not possible to bisect through your series anyway
(one needs all the patches before anything starts working really),
so from my point of view you could also write your code in a way that
expects Al's patches to get merged first.
