From 1355e2a6eb88f04d76125c057dc5fca64d4b6a9e Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 25 Jul 2012 14:32:38 +0100 Subject: ARM: mm: HugeTLB support for LPAE systems. This patch adds support for hugetlbfs based on the x86 implementation. It allows mapping of 2MB sections (see Documentation/vm/hugetlbpage.txt for usage). The 64K pages configuration is not supported (section size is 512MB in this case). Signed-off-by: Catalin Marinas [steve.capper@linaro.org: symbolic constants replace numbers in places. Split up into multiple files, to simplify future non-LPAE support, removed huge_pmd_share code, as this is very rarely executed, Added PROT_NONE support].
