xinhui pan 8e589d853f use rbtree instead of vm_objects list ...

simple test of mapping many system memory to gpu.
before
[ RUN      ] KFDMemoryTest.MMap
[          ] Using ISA for GFXIP 9.0
[          ] successfully register/map 32GB system memory to gpu
[       OK ] KFDMemoryTest.MMap (36932 ms)

after
[ RUN      ] KFDMemoryTest.MMap
[          ] Using ISA for GFXIP 9.0
[          ] successfully register/map 32GB system memory to gpu
[       OK ] KFDMemoryTest.MMap (11441 ms)

So there is 11s VS 36s improvement.

Looks like we can do something similar with vm_area too.
