Subject: [PATCH v5 3/7] powerpc/mm/hugetlb: Handle hugepage size supported by hash config
Date: Wed, 23 Nov 2016 16:39:59 +0530 [thread overview]
Message-ID: <20161123111003.459-3-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <20161123111003.459-1-aneesh.kumar@linux.vnet.ibm.com>
W.r.t hash page table config, we support 16MB and 16GB as the hugepage
size. Update the hstate_get_psize to handle 16M and 16G.
