Message:

new physical memory allocator supporting physical address constrains
the buddy allocator framework is retired and replaced by a two-level bitmap
the allocator can allocate an arbitrary number of frames, not only a power-of-two count

Caution: Change of semantics
The physical memory allocator no longer allocates naturally aligned blocks. If you require an aligned block, specify it as the constraint.
