New lmb could be used to replace early_res in x86.
Suggested by: David, Ben, and Thomas
-v6: change sequence as requested by Thomas
-v7: seperate them to more patches
-v8: add boundary checking to make sure not free partial page.
-v9: use lmb_debug to control print out of reserve_lmb.
add e820 clean up, and e820 become __initdata
-v10:use lmb.rmo_size and ARCH_DISCARD_LMB according to Michael
change name to lmb_find_area/reserve_lmb_area/free_lmb_area,
according to Michael
update find_lmb_area to use __lmb_alloc_base according to ben
-v11:move find_lmb_area_size back to x86.
x86 has own find_lmb_area, and could be disabled by ARCH_LMB_FIND_AREA
because _lmb_find_base has different behavoir from x86's old one.
one from high to high and one from low to high
need more test
tested for x86 32bit/64bit, numa/nonuma, nobootmem/bootmem.
-v12:refresh the series with current tip
seperate nobootmem.c, so could remove some #ifdef
still keep CONFIG_NO_BOOTMEM, in x86 .c, and could use the as tags
so other lmb could refer them to use NO_BOOTMEM.
-v14:refresh to current tip
-v15:remove x86 version lmb_find_area
remove other nobootmem and x86 e820 from this patchset
-v16: rebase to Ben's cleanup powerpc/lmb
move back most func back to arch/x86/mm/lmb.c
-v17: remove exposing of lmb_add_region
seperate first lmb core related patch to several small patches.
-v18: change lmb_find_area to lmb_find_in_range
kill __lmb_find_area and use lmb_find_area directly
remove lmb_add_memory
change lmb_reserve_area to lmb_reserve_range
change lmb_free_area to lmb_free_range
don't clear lmb.reserved after converting
use for_each_lmb to replace for cycle
rebase to 06/15/2010 powerpc/lmb
-v19: make the patchset only focus on lmb related.
will submit patches about bootmem/nobootmem seperating and other e820
related later after this one.
this patcheset is based on tip/master+powerpc/lmb
todo:
replace range handling (subtracting) with lmb.
