From c95221f69dfa5d3696b2b91374cbd7e5897657c5 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 9 Oct 2013 16:49:03 +0200 Subject: [PATCH] KVM: s390: Do not set CC3 for EQBS and SQBS The EQBS and SQBS instructions do not set CC3 for invalid channels, but should throw an operation exception instead when not available. Thus they should not be handled by the handle_io_inst() wrapper but drop to userspace instead (which will then inject the operation exception).
