[Qemu-devel] [PATCH 08/10] s390x/css: fix control flags during csch

[Cornelia Huck]

From: Halil Pasic <address@hidden>

>From the beginning, css support contained an error in csch handling:
instead of setting the clear bit in the function control bits twice, we
need to set the clear pending bit in the activity control bits. Let's
fix this.
