From: "David S. Miller" <davem@xxxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
[ Upstream commit ee73887e92a69ae0a5cda21c68ea75a27804c944 ]
In commit b2d438348024b75a1ee8b66b85d77f569a5dfed8 ("sparc64: Make
PAGE_OFFSET variable."), the MAX_PHYS_ADDRESS_BITS value was increased
(to 47).
This constant reference to '41UL' was missed.
