Subject: [PATCH -v24 00/50] Use memblock with x86
New memblock could be used to replace early_res in x86.
Suggested by: David, Ben, and Thomas
-v18: change memblock_find_area to memblock_find_in_range
kill __memblock_find_area and use memblock_find_area directly
remove memblock_add_memory
change memblock_reserve_area to memblock_reserve_range
change memblock_free_area to memblock_free_range
don't clear memblock.reserved after converting
use for_each_memblock to replace for cycle
rebase to 06/15/2010 powerpc/memblock
-v19: make the patchset only focus on memblock related.
will submit patches about bootmem/nobootmem seperating and other e820
related later after this one.
-v20: put ben change together...
add memblock_dbg() according to Ingo
-v21: debug print add # for 0x
removed old bootmem support for x86 according to Ingo, Thomas and HPA
change MEMBLOCK_ERROR to 0 according to Linus
-v22: change x86 related memblock to memblock_x86_ instead of according to Ingo
-v23: rename lmb to memblock before Ben's cleanup patcheset, and x86 using patches.
-v24: fold memblock_find_base() return change to orig patch (patch 20)
change to -1 display
patch 46: has to be done in one shoot to switch from early_res to memblock.
First two patches are needed for 2.6.35. need to be applied at first.
todo:
replace range handling (subtracting) with memblock.
Thanks
Yinghai Lu
