From 788be8e9d669c314ad7aef1a71bce31367cfe462 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Tue, 17 Sep 2013 10:32:54 +0200 Subject: s390/eventfacility: Fix receive/send masks Currently we announce interchanged receive/send masks. This did not trigger a bug, since the sclp console has the same masks for send/receive and the Linux guest does not check the sclp mask for simple events like quiesce. With other event users like the sclp line mode console, we will have different send/receive bits. Fix it.
