Subject: [PATCH 8/9] x86/cpuid: Introduce missing feature adjustment in calculate_pv_def_policy()
Date: Mon, 15 Jun 2020 15:15:31 +0100	[thread overview]
Message-ID: <20200615141532.1927-9-andrew.cooper3@citrix.com> (raw)
In-Reply-To: <20200615141532.1927-1-andrew.cooper3@citrix.com>

This was an accidental asymmetry with the HVM side.

No change in behaviour at this point.

Fixes: 83b387382 ("x86/cpuid: Introduce and use default CPUID policies")
