Patch series "Some bugfix about kmemleak", v3.

Some bugfixes for kmemleak and the printed info from debug mode.


This patch (of 7):

Since kmemleak_alloc_phys() rather than kmemleak_alloc() was called from
memblock_alloc_range_nid(), kmemleak_free_part_phys() should be used to
delete kmemleak object in put_page_bootmem().  In debug mode, there are
following warning:

 kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096)
