From c7fa77016eb6093df38fdabdb7a89bb9617e7185 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 19 May 2020 05:49:03 +0000 Subject: powerpc/mm: Standardise __ptep_test_and_clear_young() params between PPC32 and PPC64 On PPC32, __ptep_test_and_clear_young() takes the mm->context.id In preparation of standardising pte_update() params between PPC32 and PPC64, __ptep_test_and_clear_young() need mm instead of mm->context.id Replace context param by mm.
