From 423e2f94456404b49d89ef587c34022987a581e1 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 27 Nov 2018 19:18:05 +1100 Subject: [PATCH] powerpc/mm: Remove very old comment in hash-4k.h This comment talks about PTEs being 64-bits and PMD/PGD being 32-bits, but that hasn't been true since 2005 when David Gibson implemented 4-level page tables in the commit titled "Four level pagetables for ppc64". Remove it.
