From 13bf679e8147c11de6fd32e4fba12924908ceee5 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Wed, 13 May 2015 14:33:22 +0200 Subject: [PATCH] s390/mm: correct return value of pmd_pfn Git commit a54b8e5d1339b78880b53a29dc08548b871c8149 "s390/mm: implement dirty bits for large segment table entries" broke the pmd_pfn function, it changed the return value from 'unsigned long' to 'int'. This breaks all machine configurations with memory above the 8TB line.
