The patch titled
Subject: arc: get rid of superfluous __GFP_REPEAT
has been removed from the -mm tree. Its filename was
arc-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@xxxxxxxx>
Subject: arc: 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.
pte_alloc_one_kernel uses __get_order_pte but this is obviously always
zero because BITS_FOR_PTE is not larger than 9 yet the page size is always
larger than 4K. This means that this flag has never been actually useful
here because it has always been used only for PAGE_ALLOC_COSTLY requests.
