[PATCH 07/19] mips: get rid of superfluous __GFP_REPEAT

From: Michal Hocko
Date: Mon Apr 11 2016 - 07:10:52 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}, pmd_alloc_one allocate PTE_ORDER resp. PMD_ORDER
but both are not larger than 1. This means that this flag has never
been actually useful here because it has always been used only for
PAGE_ALLOC_COSTLY requests.
