In x86 mm code there are multiple instances of page table walks for
different purposes.
Introduce a generic page table walker being able to cover the current
use cases. It will be used for other cases in future, too.
The page table walker needs some per-level data, so add a table for
that data. Merge it with the already existing pt_prot[] array.
Rewrite get_pgt() to use the new walker.

Samuel - I've taken the liberty to convert the odd upper-case A.
Jürgen - looking at the mini-os short-log is quite odd, and increasingly
so. In the mini-os repo surely all commits are about mini-os; the
subject prefixes are kind of pointless. To nevertheless identify such
patches on xen-devel@, may I suggest to use (taking this patch as an
example) "[PATCH MINI-OS] mm: introduce generic page table walk function"
instead (or, of course, whatever variation thereof you may like better)?
Okay, fine with me.
Juergen
