Date: Fri, 10 Aug 2012 21:24:55 -0400 From: Cyril Chemparathy <cyril@...com> To: <linux-kernel@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org> CC: <arnd@...db.de>, <catalin.marinas@....com>, <grant.likely@...retlab.ca>, <nico@...aro.org>, <linux@....linux.org.uk>, <will.deacon@....com>, Cyril Chemparathy <cyril@...com>, Vitaly Andrianov <vitalya@...com> Subject: [PATCH v2 12/22] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem 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.
