From 0d9fc36580094c63e3411b8b00409d2706c0efb7 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Fri, 15 Dec 2017 10:20:38 -0500 Subject: [PATCH] powerpc/mm/hugetlb: Allow runtime allocation of 16G. BugLink: http://bugs.launchpad.net/bugs/1706247 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.
