It looks like bufpages is currently set in allocsys(), which is called quite
early on some architectures. arm26 and alpha certainly call it long before
UVM is initialised. There's no reason for bufpages to be set this early,
though (since actually allocating them needs UVM to be up), so it should
perhaps go somewhere else. main() seems like the obvious place to me.

little less painful.
