- Thread-topic: [PATCH v1] x86/hvm: Update code in HVMOP_altp2m_set_suppress_ve
Originally the gfn and altp2m_idx are assigned from the a.u.mem_access union.
This works because it's the same memory used. This patch addresses this
issue by changing the mem_access union with the suppress_ve union for
consistency.
