It is, normally. Nobody thought about this case.

Duplicating the same stuff in multiple places is the larger sin. It sounds
like the best compromise would be to kernel-doc the interface in the .h
file and remove the duplicated comments from .c.

Or perhaps we kernel-doc the interface in the x86 .c files and leave it at
that - people should go there to find the docs. Problem is, this will
presumably generate bad results if one builds the formal kerneldoc output
for a different architecture. The kerneldoc system could of course fix
this somehow, but I don't know what shape it would take nor how much work
it would be.
