[PATCH RFCv3 2/9] s390x/diag: no need to check for PGM_PRIVILEGED in diag308

[David Hildenbrand]

Whenever we reach this point via KVM or TCG, we already verified that we
are running in the supervisor state.

TCG checks this via IF_PRIV, KVM checks this directly in the diag
instruction handler, before exiting to userspace.
