H A D | intercept.c | diff f379aae558b8daff0f7a1c5fc225af5d35c741f7 Thu Dec 20 15:32:10 CET 2012 Cornelia Huck <cornelia.huck@de.ibm.com> KVM: s390: In-kernel handling of I/O instructions.
Explicitely catch all channel I/O related instructions intercepts in the kernel and set condition code 3 for them.
This paves the way for properly handling these instructions later on.
Note: This is not architecture compliant (the previous code wasn't either) since setting cc 3 is not the correct thing to do for some of these instructions. For Linux guests, however, it still has the intended effect of stopping css probing.
