From 6fb12766f7fcd7934b09fbfbd32a725cc2febf96 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 23 Sep 2019 15:35:25 -0700 Subject: [PATCH] sh: switch to generic version of pte allocation The sh implementation pte_alloc_one(), pte_alloc_one_kernel(), pte_free_kernel() and pte_free() is identical to the generic except of lack of __GFP_ACCOUNT for the user PTEs allocation. Switch sh to use generic version of these functions.
