From acc7fa17e6fe96bd68ad9af04fde5091383ef25e Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Mon, 23 Apr 2018 18:51:18 +0200 Subject: pc-dimm: no need to pass the memory region We can just query it ourselves. When unplugging, we should always be able to the region (as it was previously plugged). E.g. PPC already assumed that and used &error_abort.
