Subject: [PATCH V2 1/3] x86/Hyper-V: Fix definition of struct hv_vp_assist_page
From: Tianyu Lan <Tianyu.Lan@...rosoft.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.
Signed-off-by: Tianyu Lan <Tianyu.Lan@...rosoft.com>

Change since v1:
Move definition of struct hv_nested_enlightenments_control
into this patch to fix offset issue.
