Registering Mapped Linux Character Device Memory with cudaHostRegister Results in Invalid Argument

Hi,

After I’ve published my topic on :
https://devtalk.nvidia.com/default/topic/1014391/cuda-programming-and-performance/registering-mapped-linux-character-device-memory-with-cudahostregister-results-in-invalid-argument/
I’ve noticed that this section is much more suitable, so I’ll just leave it in here.

Thanks a lot.
