Subject: [PATCH 11/22] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem
Date: Tue, 31 Jul 2012 19:04:47 -0400 [thread overview]
Message-ID: <1343775898-28345-12-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1343775898-28345-1-git-send-email-cyril@ti.com>
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.
