From 4722476bce283149986a3463f61009dec0e7f6a1 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 10 Nov 2017 04:27:40 +1100 Subject: powerpc/64s: mm_context.addr_limit is only used on hash Radix keeps no meaningful state in addr_limit, so remove it from radix code and rename to slb_addr_limit to make it clear it applies to hash only.
