[PATCH 05/17] x86,memblock: Add memblock_x86_reserve_range/memblock_x86_free_range
they are wrappers for core versions. they are taking start/end/name instead of base/size. will make x86 conversion more easy could add more debug print out -v2: change get_max_mapped() to memblock.default_alloc_limit according to Michael Ellerman and Ben change to memblock_x86_reserve_range and mem... 29 Jul 2010 16:18

[PATCH 13/17] x86: Use memblock to replace early_res
1. replace find_e820_area with memblock_find_in_range 2. replace reserve_early with memblock_x86_reserve_range 3. replace free_early with memblock_x86_free_range. 4. NO_BOOTMEM will switch to use memblock too. 5. use _e820, _early wrap in the patch, in following patch, will replace them all 6. because memblock... 29 Jul 2010 16:18

[PATCH 02/17] x86, memblock: Add memblock_x86_find_in_range_size()
size is returned according free range. Will be used to find free ranges for early_memtest and memory corruption check Do not mess it up with lib/memblock.c yet.

[PATCH 11/17] x86, memblock: Add memblock_x86_memory_in_range()
It will return memory size in specified range according to memblock.memory.region Try to share some code with memblock_x86_free_memory_in_range() by passing get_free to __memblock_x86_memory_in_range(). -v2: Ben want _in_range in the name instead of size Signed-off-by: Yinghai Lu <yinghai(a)kernel.org> --- a... 29 Jul 2010 16:18

[PATCH 10/17] x86, memblock: Add memblock_x86_free_memory_in_range()
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 memblock.memory.region. Use memblock.memory.region subtracting memblock.reserved.region to get free range array. then count size of all free ranges. -v2: ... 29 Jul 2010 16:18

[PATCH 06/17] x86, memblock: Add get_free_all_memory_range()
get_free_all_memory_range is for CONFIG_NO_BOOTMEM=y, and will be called by free_all_memory_core_early(). It will use early_node_map aka active ranges subtract memblock.reserved to get all free range, and those ranges will convert to slab pages. -v4: increase range size Signed-off-by: Yinghai Lu <yinghai(a)ker... 29 Jul 2010 16:18

[PATCH 12/17] x86, memblock: Use memblock_debug to control debug message print out
Also let memblock_x86_reserve_range/memblock_x86_free_range could print out name if memblock=debug is specified will also print ther name when reserve_memblock_area/free_memblock_area are called. -v2: according to Ingo, put " if (memblock_debug) " in one place Signed-off-by: Yinghai Lu <yinghai(a)kernel.org> -... 29 Jul 2010 16:18
