x86: fix memory setup bug
interesting... [ 0.000000] mapped low ram: 0 - 20000000 [ 0.000000] low ram: 00000000 - 1fff0000 [ 0.000000] bootmap 00002000 - 00006000 max_pfn_mapped > max_low_pfn? it seems init_memory_mapping reveals an old bug. please check attached test patch. Signed-off-by: Ingo Molnar <mingo@elte.hu>
