From cf1b09908a231f3bb5e8ca15b76f05c4df91e292 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 1 Sep 2017 03:39:46 +0100 Subject: [PATCH] ARM: 8693/1: discard memblock arrays when possible On ARM the generic pfn_valid() version is used with some configurations such as SA1100 based devices. In that case the memblock arrays are no longer used after boot and can be discarded.
