Hi Arnd,
I'm slightly curious to know how you configured the kernel to build
the Netronome NFP driver but not CRC32 but nonetheless I have no
objection to this change.
For the Netronome portion:

I ran into one link error on a randconfig build and then tried an 'allyesconfig'
configuration, turning everything off manually that selects CRC32.
Working through the resulting link errors ended up being more work than I was
planning for though, so I don't recommend reproducing this. I have another 25
patches for other subsystems.

Applied, thanks!
