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.
