Great! Please let us know when this makes it into the official kernel
(so we have some assurance the interface is stable) and I'll add
support in musl as soon as we can find a system to test it on. Unless
there's any gratuitous incompatibility with vdso on other archs,
adding it on our side should be just a three-line patch to
arch/arm/syscall_arch.h.
