Subject: [PATCH 1/3] x86/Hyper-V: Fix definition of struct hv_vp_assist_page
Date: Fri, 9 Aug 2019 17:49:37 +0800 [thread overview]
Message-ID: <20190809094939.76093-2-Tianyu.Lan@microsoft.com> (raw)
In-Reply-To: <20190809094939.76093-1-Tianyu.Lan@microsoft.com>
From: Tianyu Lan <Tianyu.Lan@microsoft.com>
The struct hv_vp_assist_page was defined incorrectly.
The "vtl_control" should be u64[3], "nested_enlightenments_control"
should be a u64 and there is 7 reserved bytes following "enlighten_vmentry".
This patch is to fix it.
