Commit Message

Cornelia Huck June 21, 2021, 9:58 a.m. UTC 
With commit 0280b3eb7c05 ("s390x/kvm: use cpu model for gscb on
compat machines"), we removed any calls to kvm_s390_get_gs()
in favour of a different mechanism.

Let's remove the unused kvm_s390_get_gs(), and with it the now
unneeded cap_gs as well.
