[PATCH] consolidate asm/futex.h
Most of the architectures have the same asm/futex.h. This consolidates them
into asm-generic, with the arches including it from their own asm/futex.h.
In the case of UML, this reverts the old broken futex.h and goes back to using
the same one as almost everyone else.
