No objections have been noted previously, and in addition this has a
vDSO equivalent on on x86_64, x32, and 64-bit ppc kernels. I haven't
added support for that yet, but I'm hoping to make that my next patch if
this gets merged.
Shoving the raw syscall into every app seems unproductive, and adding
vDSO handling to random userland apps seems especially odd.
I *started* this patch because a patch of mine to support musl in an
application was denied, on grounds of the syscall handling belonging in
libc.
