[PATCH 13/29] lmb: Add lmb_free_memory_size()
It will return free memory size in specified range. We can not use memory_size - reserved_size here, because some reserved area may not be in the scope of lmb.memory.region. Use lmb.memory.region subtracting lmb.reserved.region to get free range array. then count size of all free ranges. Signed-off-by: Yingh... 30 Mar 2010 08:19

[PATCH 07/29] lmb: Add lmb_to_bootmem()

[PATCH 06/29] bootmem, x86: Add weak version of reserve_bootmem_generic
It will be used lmb_to_bootmem converting It is an wrapper for reserve_bootmem, and x86 64bit is using special one. Also clean up that version for x86_64. We don't need to take care of numa path for that, bootmem can handle it how Signed-off-by: Yinghai Lu <yinghai(a)kernel.org> --- arch/x86/mm/init_32.c | ... 30 Mar 2010 08:19
