KVM: s390: vsie: Fix length of facility list shadowed2023-12-23T09:41:09ZNina Schoetterl-Glausch2023-12-19T14:08:51Zurn:sha1:682dbf430d27bc0e23d8d6921116b4f77f5dc9c6
The length of the facility list accessed when interpretively executing
STFLE is the same as the hosts facility list (in case of format-0)
The memory following the facility list doesn't need to be accessible.
The current VSIE implementation accesses a fixed length that exceeds the
guest/host facility list length and can therefore wrongly inject a
validity intercept.
Instead, find out the host facility list length by running STFLE and
copy only as much as necessary when shadowing.
