[PATCH] uml: merge duplicated page table code
There is a lot of code which is duplicated between the 2 and 3 level implementation, with the only difference that the 3-level implementation is a bit more generalized (instead of accessing directly pte_t.pte, it uses the appropriate access macros). So this code is joined together. As obvious, a "core code nice cleanup" is not a "stability-friendly patch" so usual care applies.
