From b0124ff57e9405725b4dfeffbdfa929bb973ad2c Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 26 Apr 2019 15:58:07 +0000 Subject: [PATCH] powerpc/mm: inline pte_alloc_one_kernel() and pte_alloc_one() on PPC32 pte_alloc_one_kernel() and pte_alloc_one() are simple calls to pte_fragment_alloc(), so they are good candidates for inlining as already done on PPC64.
