Subject: [PATCH v3 RESEND 12/17] ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem
Date: Fri, 21 Sep 2012 11:56:10 -0400 [thread overview]
Message-ID: <1348242975-19184-13-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1348242975-19184-1-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.
