From mboxrd@z Thu Jan 1 00:00:00 1970 From: cyril@ti.com (Cyril Chemparathy) Date: Tue, 24 Jul 2012 01:10:24 -0000 Subject: [RFC 13/23] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem In-Reply-To: <1343092165-9470-1-git-send-email-cyril@ti.com> References: <1343092165-9470-1-git-send-email-cyril@ti.com> Message-ID: <1343092165-9470-14-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.
