From 57e2a99f74b0d3720c97a6aadb57ae6aad3c61ea Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 28 Jul 2009 11:59:34 +1000 Subject: powerpc: Add memory management headers for new 64-bit BookE This adds the PTE and pgtable format definitions, along with changes to the kernel memory map and other definitions related to implementing support for 64-bit Book3E. This also shields some asm-offset bits that are currently only relevant on 32-bit We also move the definition of the "linux" page size constants to the common mmu.h file and add a few sizes that are relevant to embedded processors.
