Yinghai Lu f96f57d91c x86: fix init_memory_mapping for [dc000000 - e0000000) - v2 ... Impact: change over-mapping to precise mapping, fix /proc/meminfo output v2: fix less than 1G ram system handling when gart aperture is 0xdc000000 - 0xe0000000 it return 0xc0000000 - 0xe0000000 that is not right. this patch fix that will get exact mapping on 256g sytem with that aperture after patch LBSuse:~ # cat /proc/meminfo MemTotal: 264742432 kB MemFree: 263920628 kB Buffers: 1416 kB Cached: 24468 kB ...
