[RFC 13/23] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem

From: Cyril Chemparathy
Date: Mon Jul 23 2012 - 21:11:34 EST

This patch adds an architecture defined override for ARCH_LOW_ADDRESS_LIMIT.
On PAE systems, the absence of this override causes bootmem to incorrectly
limit itself to 32-bit addressable physical memory.
