walk_page_range() is going to be allowed to walk page tables other than
those of user space. For this it needs to know when it has reached a
'leaf' entry in the page tables. This information will be provided by the
p?d_large() functions/macros.
I can't remember whether or not I asked this before, but why not call
this macro p?d_leaf() if that's what it's identifying? "Large" and "huge"
are usually synonymous, so I find this naming needlessly confusing based
on this patch in isolation.
You replied to my posting of this patch before[1], to which you said:

I've have thought p?d_leaf() might match better with your description
above, but I'm not going to quibble on naming.
That explains the sense of deja vu.
Have you changed your mind about quibbling? ;)
Ha, I suppose I have! If it's not loads of effort to use p?d_leaf() instead
of p?d_large, then I'd certainly prefer that.
