The comment about steal_context() came from powerpc and a part of it
addresses differences between powerpc variants that are not really
relevant to m68k.
Remove that part of the comment.

Do you want me to carry that in my m68k (m68knommu) tree for v5.9?

Hi,
I've found this by pure chance while grepping for pgalloc.h
It's been there since 2011, but I don't think it's a stable material, so I
didn't cc them.
