description:
uvm_extern.h is has both a _KERNEL only, and a non _KERNEL only API.

Since we unconditionally expose the uvm_physseg.h API via uvm_extern.h
right now, and since uvm_physseg.h uses a kernel only datatype, viz
psize_t, we restrict exposure of uvm_physseg.h API exposure to kernel
only.

This is in conformance of its documentation via uvm_hotplug(9) as a
kernel internal API.
