[PATCH 09/17] parisc: get rid of superfluous __GFP_REPEAT

From: Michal Hocko
Date: Mon May 30 2016 - 05:17:50 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.

pmd_alloc_one allocate PMD_ORDER which is 1. This means that this flag
has never been actually useful here because it has always been used only
for PAGE_ALLOC_COSTLY requests.
