From: "Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>

Copy sys_futex64-allows-64bit-futexes-workaround.patch to UML (to unbreak
the UML build).  Note however that in include/asm-generic/futex.h we have:

static inline int
futex_atomic_cmpxchg_inatomic(int __user *uaddr, int oldval, int newval)
{
	return -ENOSYS;
}

Which is a better solution. Pierre Peiffer, please consider that.
