From 4722b8feb0dc53a01a051f36846bef5a95d91a46 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 15 Nov 2015 11:36:29 +0100 Subject: m68k/mm: m54xx - Add missing initialization of max_pfn If max_pfn is not initialized, the various /proc/kpage* files are empty, and selftests/vm/mlock2-tests will fail. max_pfn is also used by the block layer to calculate DMA masks.
