From 410f14837a92177242a403c20d0a0906fe357019 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 14 Feb 2011 12:58:04 +0100 Subject: ARM: 6667/1: Fix early_pte_alloc() assumption about the Linux PTE With LPAE we no longer have software bits in a separate Linux PTE and the early_pte_alloc() function should pass PTE_HWTABLE_OFF + PTE_HWTABLE_SIZE to early_alloc() to avoid allocating extra memory.
