# HG changeset patch # User Isaku Yamahata <yamahata@xxxxxxxxxxxxx> # Date 1222310873 -32400 # Node ID 325904748847d17e8a6999da1a208b01ce9d90cf # Parent 6055360dbfe4848682ee8c65bce19c57e1728034 [IA64] A small fix in mm.c. Use PAGE_MASK, not ~PAGE_MASK. ~PAGE_MASK was wrongly used to get page aligned address. Use PAGE_MASK, not ~PAGE_MASK.
