src/sys/rump/librump/rumpkern: lwproc.c rumpkern.ifspec
Log Message:
Support multiple syscall emuls.
Rump kernels with only local clients have it easy, since they have to
support at most two syscall vectors (some calls such as mount/unmount
can be made only through the "native" NetBSD vector). Remote clients
are a whole different tin of green beans. This change addresses local
clients only.
