From a110655a068d4b98495115ff0f8405235d845272 Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Wed, 6 Apr 2016 10:36:06 +0530 Subject: [PATCH] spapr: Fix ibm,lrdr-capacity ibm,lrdr-capacity has a field to describe the maximum address in bytes and therefore, the most memory that can be allocated to this guest. We are using maxmem for this field, but instead should use the actual RAM address corresponding to the end of hotplug region.
