For most drivers in drivers/crypto they will need multiple header
files included by kernel.h.  I'd hate for people to start posting
patches replacing one inclusion of kernel.h with multiple inclusions.

They're bound to get it wrong and we'll be forever dealing with
random build failures because someone changes a random header
elsewhere which then exposes a missed inclusion.

Cheers,
