The patch titled

has been removed from the -mm tree.  Its filename was
     opeinrisc-switch-to-generic-version-of-pte-allocation.patch

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

From: Mike Rapoport <rppt@linux.ibm.com>
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.
