From: Paul Mundt Date: Mon, 7 Nov 2005 08:58:23 +0000 (-0800) Subject: [PATCH] sh: pte_mkhuge() compile fix for !CONFIG_HUGETLB_PAGE X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d229401f130941583eb46a2e8886df61241c14eb;p=deliverable%2Flinux.git [PATCH] sh: pte_mkhuge() compile fix for !CONFIG_HUGETLB_PAGE Presently it is bogus to call pte_mkhuge() outside of the CONFIG_HUGETLB_PAGE context, as the only processors that support _PAGE_SZHUGE do so in the hugetlbpage context only (and this is the only time that _PAGE_SZHUGE is even defined). SH-2 and SH-3 do not support huge pages at all, and so it is not possible to enable this.
