New beta driver 378.09 has been released, and details are here:  http://www.nvidia.com/download/driverResults.aspx/114232/en-us

The driver compiles OK with Kernel 4.9.4, but fails to compile with 4.10-rc4, with different errors from 375.26, as some of the code base has changed..

And.. as expected, the patch for 375.26 does not work, as some of the code, headers, etc. are different, or files no longer exist:

Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

So, for the time being, stay with 375.26 (patched) on 4.10-rc…
