See if you can change these to `ssize_t ... void *buf ...' so that they
actually match their application interface. Changing the return type
seems to be hard - it seems to require changing all syscalls to return
(signed) register_t.

Probably shouldn't be supported on new arches.

Certainly shouldn't be supported on new arches (were superseded by sysctls).
