From: Thomas Huth Date: Wed, 9 Oct 2013 14:49:03 +0000 (+0200) Subject: KVM: s390: Do not set CC3 for EQBS and SQBS X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c95221f69dfa5d3696b2b91374cbd7e5897657c5;p=openwrt%2Fstaging%2Fblogic.git 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).
