I am downgrading as I verified there is a working workaround, add the
following to the kernel cmdline:

slab_common.usercopy_fallback=y

It might be possible to fix, and someone at gr security published a
patch that among other things changes the module to use the correct API
(although for an older version):

https://www.grsecurity.net/~paxguy1/nvidia-drivers-387.12-pax.patch

but given it's non-trivial and there is a working cmdline workaround,
I'm not going to try and apply that patch, and Nvidia is looking into
it.
