Subject: [PATCH AUTOSEL 4.9 1/3] s390/hypfs: avoid error message under KVM

From: Juergen Gross <jgross@...e.com>

[ Upstream commit 7b6670b03641ac308aaa6fa2e6f964ac993b5ea3 ]

When booting under KVM the following error messages are issued:

hypfs.7f5705: The hardware system does not support hypfs
hypfs.7a79f0: Initialization of hypfs failed with rc=-61

Demote the severity of first message from "error" to "info" and issue
the second message only in other error cases.
