Shortly, I will doing something about the sun4c's cache aliasing problem.
This will involve a slight re-arrangement of VM routines that may result
in different virtual address (when using mmap(2) calls).

All this uncovered a bug in the run-time linker (ld.so) causing shared
library segments to end up on top of each other. So, it is necessary to
update ld.so before booting a kernel with the VM mods in it.
