Hi DRM folks,

we'd like to start using drm_mm in bpf arena.
The drm_mm logic fits particularly well to bpf use case.
See individual patches.

objdump -h lib/drm_mm.o 
.text         000012c7

So no vmlinux size concerns.

Alexei Starovoitov (2):
  drm, bpf: Move drm_mm.c to lib to be used by bpf arena
  bpf: Switch bpf arena to use drm_mm instead of maple_tree
