the new lmb could be used to 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. still keep find_lmb_area, may replace those find_lmb_area will lmb_alloc, if everything go fine Please put them into tip and -next to have more test coverage.
