Linux v2.6.15-rc5

Hey, for no other reason than the fact that I'll be off-line for a
week.

Of course, I could force everybody to just use git (and when I'm emperor
of the world, don't think I won't!), but it seems some people want to
just test official releases.  Even if they are just -rc's.

By the time I'm back, Andrew will have fixed all my bugs, and I'll
release it as 2.6.15 and take all the credit.

Mwahahahaaa
