Subject: [PATCH 07/15] hyperv: dedup cpuid definitions
Date: Tue, 20 Dec 2016 18:55:54 +0300	[thread overview]
Message-ID: <20161220155602.6298-8-rkagan@virtuozzo.com> (raw)
In-Reply-To: <20161220155602.6298-1-rkagan@virtuozzo.com>

Use the definitions already present in the uapi header throughout the
guest driver, too.
