Subject: [PATCH] XFS:  Replace remaining memclear_highpage_flush() with
 zero_user_page().

  this appears to be the final occurrence of that deprecated call in
the entire tree which suggests that, if you're not concerned about
out-of-tree modules, that definition could also be removed from
include/linux/highmem.h:

static inline void __deprecated memclear_highpage_flush(struct page *page,
                        unsigned int offset, unsigned int size)
{
        zero_user_page(page, offset, size, KM_USER0);
}
