From mboxrd@z Thu Jan 1 00:00:00 1970 From: cyril@ti.com (Cyril Chemparathy) Date: Fri, 10 Aug 2012 21:24:55 -0400 Subject: [PATCH v2 12/22] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem In-Reply-To: <1344648306-15619-1-git-send-email-cyril@ti.com> References: <1344648306-15619-1-git-send-email-cyril@ti.com> Message-ID: <1344648306-15619-13-git-send-email-cyril@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
