This patch was dropped because it was merged into mainline or a subsystem tree

From: Mike Rapoport <[email protected]>
Subject: opeinrisc: switch to generic version of pte allocation

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.
