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:

This patch (of 4):
Remove the unused kmemleak_not_leak_phys() function. And remove the
min_count argument to kmemleak_alloc_phys() function, assume it's 0.
