| From | Cyril Chemparathy <> | Subject | [RFC 13/23] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem | Date | Mon, 23 Jul 2012 21:09:15 -0400 |
| |
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.
