From dcfdae04bd92e8a2ea155db0e21e3bddc09e0a89 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Tue, 22 Nov 2011 17:30:29 +0000 Subject: ARM: LPAE: Introduce the 3-level page table format definitions This patch introduces the pgtable-3level*.h files with definitions specific to the LPAE page table format (3 levels of page tables). Each table is 4KB and has 512 64-bit entries. An entry can point to a 40-bit physical address. The young, write and exec software bits share the corresponding hardware bits (negated). Other software bits use spare bits in the PTE. The patch also changes some variable types from unsigned long or int to pteval_t or pgprot_t.
