The patch titled
mm: remove GFP_HIGHUSER_PAGECACHE
has been removed from the -mm tree. Its filename was
mm-remove-gfp_highuser_pagecache.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: mm: remove GFP_HIGHUSER_PAGECACHE
From: Hugh Dickins <hugh@xxxxxxxxxxx>
GFP_HIGHUSER_PAGECACHE is just an alias for GFP_HIGHUSER_MOVABLE, making
that harder to track down: remove it, and its out-of-work brothers
GFP_NOFS_PAGECACHE and GFP_USER_PAGECACHE.
Since we're making that improvement to hotremove_migrate_alloc(), I think
we can now also remove one of the "o"s from its comment.
