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?
