[PATCH 08/20] nios2: get rid of superfluous __GFP_REPEAT

From: Michal Hocko
Date: Thu Apr 28 2016 - 09:29:44 EST


From: Michal Hocko <mhocko@xxxxxxxx>

__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} allocate PTE_ORDER which is 0. This means that
this flag has never been actually useful here because it has always been
used only for PAGE_ALLOC_COSTLY requests.
