Patrick Wang c200d90049 mm: kmemleak: remove kmemleak_not_leak_phys() and the min_count argument to kmemleak_alloc_phys()
Patch series "mm: kmemleak: store objects allocated with physical address
separately and check when scan", v4.

The kmemleak_*_phys() interface uses "min_low_pfn" and "max_low_pfn" to
check address.  But on some architectures, kmemleak_*_phys() is called
before those two variables initialized.  The following steps will be
taken:

1) Add OBJECT_PHYS flag and rbtree for the objects allocated
   with physical address
2) Store physical address in objects if allocated with OBJECT_PHYS
3) Check the boundary when scan instead of in kmemleak_*_phys()

This patch set will solve:
