From b5048de04b32104140e5b251005404c3e0d03ccd Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 1 Aug 2017 20:29:23 +1000 Subject: [PATCH] powerpc/mm/slb: Move comment next to the code it's referring to There is a comment in slb_allocate() referring to the load of paca->vmalloc_sllp, but it's several lines prior in the assembly. We're about to change this code, and we want to add another comment, so move the comment immediately prior to the instruction it's talking about.
