[merged] arm-get-rid-of-superfluous-__gfp_repeat.patch removed from -mm tree

[akpm]

The patch titled
     Subject: arm: get rid of superfluous __GFP_REPEAT
has been removed from the -mm tree.  Its filename was
     arm-get-rid-of-superfluous-__gfp_repeat.patch

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

------------------------------------------------------
From: Michal Hocko <mhocko@suse.com>
Subject: arm: get rid of superfluous __GFP_REPEAT

__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.

PGALLOC_GFP uses __GFP_REPEAT but none of the allocation which uses this
flag is for more than order-2.  This means that this flag has never been
actually useful here because it has always been used only for
PAGE_ALLOC_COSTLY requests.
