Ard Biesheuvel 5bd4669471 arm64/mm: remove pointless map/unmap sequences when creating page tables 
The routines __pud_populate and __pmd_populate only create a table
entry at their respective level which refers to the next level page
by its physical address, so there is no reason to map this page and
then unmap it immediately after.
