From e2b8d7af0e3a9234de06606f9151f28cf847a8d6 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Mon, 25 Oct 2010 16:10:14 +0200 Subject: [S390] add support for nonquiescing sske Improve performance of the sske operation by using the nonquiescing variant if the affected page has no mappings established. On machines with no support for the new sske variant the mask bit will be ignored.
