RH-MergeRequest: 321: Enable Secure Execution Crypto Passthrough for KVM on s390x
RH-Bugzilla: 2111390
RH-Acked-by: Cédric Le Goater <clg@redhat.com>
RH-Commit: [3/5] f1329f5ce5f66033ead7777384dcc1613cad1226
Upstream Status: rhel-only
This hunk is part of upstream commit da3c22c74a3c
("linux-headers: Update to Linux v6.6-rc1"), but since that
commit updates a lot of files and does not apply cleanly,
we only focus on the necessary change here.
