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.
