[Qemu-devel] [PATCH 03/10] s390x/kvm: pass the SIGP instruction parameter to the SIGP handler |
Date: |
Tue, 24 Feb 2015 14:15:24 +0100 |
From: David Hildenbrand <address@hidden>
The parameter of the SIGP instruction will be neded in the future. Let's read it
out and store it in the struct sigp_info, so it can be passed to the sigp
handlers.
