Cover letter [PATCH -v12 00/39] use lmb with x86

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.

Thanks

Yinghai
