With AF_ALG and cryptodev, the SG is in highmem. Verified with some

Then fix AF_ALG and cryptodev, because all of the other drivers might
be affected.
No it's the driver that needs to be fixed. Of course if

If the scatter list passed by AF_ALG can be in highmem, I guess it's
the case for every driver out there. Almost every kernel code I've
