I say print it unconditionally.  Not to completely overdesign this, but
I do think we should try to at least mirror the terminology that smaps uses:

	KernelPageSize:        4 kB
	MMUPageSize:           4 kB

So definitely call this kernelpagesize.

It appears that powerpc is the only architecture where there is a
difference, and I'm not sure that this is very common at all these days.
 Do we need mmupagesize in numa_maps too?
