[PATCH v3 12/17] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem

From: Cyril Chemparathy <hidden>
Date: 2012-09-11 17:39:39
Also in: lkml
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

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.
