From d2f15e0979ee779649dec730cf17511b6f79e5be Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 21 Feb 2019 19:08:41 +0000 Subject: powerpc/32: always populate page tables for Abatron BDI. When CONFIG_BDI_SWITCH is set, the page tables have to be populated allthough large TLBs are used, because the BDI switch knows nothing about those large TLBs which are handled directly in TLB miss logic.
