Use memblock with x86

New memblock could be used to replace early_res in x86.

Suggested by: David, Ben, and Thomas

-v25: update to mainline with kmemleak fix on nobootmem
also rename lmb to memblock alread in mainline

-v26: according to Linus and hpa, seperate the big patchset to small ones.

-v27: rebase to Ben's powerpc/memblock
add memblock_free_reserved_regions() so don't need to export init regions

this one is x86 related, finally we can remove bootmem code in x86 and early_res code.

Thanks
