Ack it all except that detail in 6/10 as I'm unconvinced about ksm
pages having to return 1 on PageAnon check. I believe they deserve a
different bitflag in the mapping pointer. The smallest possible
alignment for mapping pointer is 4 on 32bit archs so there is space
for it and later it can be renamed EXTERNAL to generalize. We shall
make good use of that bitflag as it's quite precious to introduce
non-linearity in linear vmas, and not wire it to KSM only. But in
meantime we'll get better testing coverage by not having that PageKsm
== PageAnon invariant I think that I doubt we're going to retain (at
least with this implementation of PageKsm).
