[akpm@linux-foundation.org]

The patch titled
     Subject: arm: mm: add p?d_leaf() definitions
has been removed from the -mm tree.  Its filename was
     arm-mm-add-pd_leaf-definitions.patch

This patch was dropped because it was merged into mainline or a subsystem tree

From: Steven Price <steven.price@arm.com>
Subject: arm: mm: add p?d_leaf() definitions

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 is provided by the
p?d_leaf() functions/macros.

For arm pmd_large() already exists and does what we want.  So simply
provide the generic pmd_leaf() name.
