From 4ae279c2c96ab38a78b954d218790a8f6db714e5 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Fri, 28 Jul 2017 10:31:27 +0530 Subject: [PATCH] powerpc/mm/hugetlb: Allow runtime allocation of 16G. Now that we have GIGANTIC_PAGE enabled on powerpc, use this for 16G hugepages with hash translation mode. Depending on the total system memory we have, we may be able to allocate 16G hugepages runtime. This also remove the hugetlb setup difference between hash/radix translation mode.
