The patch titled
Subject: powerpc: mm: add p?d_leaf() definitions
has been removed from the -mm tree. Its filename was
powerpc-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@xxxxxxx>
Subject: powerpc: 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 powerpc p?d_is_leaf() functions already exist. Export them using the
new p?d_leaf() name.
