From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Replace pte_alloc_one(), pte_free() and pte_free_kernel() with the generic
implementation. The only actual functional change is the addition of
__GFP_ACCOUT for the allocation of the user page tables.
The pte_alloc_one_kernel() is kept back because its implementation on
openrisc is different than the generic one.
