Subject: [PATCH v4 3/8] KVM: x86: hyperv: use defines when parsing hypercall parameters
Date: Wed, 16 May 2018 17:21:26 +0200 [thread overview]
Message-ID: <20180516152131.30689-4-vkuznets@redhat.com> (raw)
In-Reply-To: <20180516152131.30689-1-vkuznets@redhat.com>
Avoid open-coding offsets for hypercall input parameters, we already
have defines for them.
