Subject: bootmem: use kmemleak_free_part_phys in free_bootmem_page
Date: Wed, 18 Oct 2023 18:29:47 +0800
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 free_bootmem_page(). In debug mode, there are
following warning:
kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096)
