Subject: ARM: LPAE: define ARCH_LOW_ADDRESS_LIMIT for bootmem
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=3d2b5a33000dac3b0ca8a1caef4a203bd0262b4c;p=people%2Faperard%2Flinux-arndale.git

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.
