generic changes for memblock

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.

This one is rebase of Ben's changeset to current mainline/tip

Last 6 are needed for x86 memblock transistion, but change mm/memblock.c

Thanks
