If anyone has any objections, please let me know. ------------------ From: "David S. Miller" <davem@...emloft.net> [ 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. Signed-off-by: David S.
