Subject: [PATCH v1] x86: hyperv: report value of misc_features
Date:   Tue,  7 Apr 2020 19:27:39 +0200
Message-Id: <20200407172739.31371-1-olaf@aepfle.de>

Precedence: bulk

A few kernel features depend on ms_hyperv.misc_features, but unlike its
siblings ->features and ->hints, the value was never reported during boot.
