Use the gpuaddr to determine whether memstore is being mapped in mmap or a normal memory allocation is mapped instead of physical address. gpuaddr of the memstore will always be unique but the physaddr may be equal to the gpuaddr of another memory allocation and that will cause the memory allocation to be mapped as memstore which is wrong.
