x86/Hyper-V: Fix definition of struct hv_vp_assist_page (7a83247e) · Commits · 戴 / test

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 are 7 reserved bytes following "enlighten_vmentry". Fix the definition. Signed-off-by:
