mainline inclusion from mainline-v6.7-rc1 commit 80203f1ca086835100843f1474bd6dd4a48cc73b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAR7B3
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
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)
