[PATCH 00/37] KFD dGPU topology and initialization

[Felix Kuehling]

This patch series adds support for dGPU topology to KFD and implements
everything needed to initialize KFD on dGPUs.

This is still missing dGPU memory management APIs, so it's not going to
be able to run any user mode tests yet. But device information about CPUs
and supported dGPUs should be reported correctly in
/sys/class/kfd/kfd/topology/nodes/*.

Patches 1-10 are small fixes and additions to the topology code.
Patches 11-19 reorganize the topology code to prepare for dGPU support.
Patches 20 and 21 add topology support for CPUs and dGPUs respectively.
Patches 22-28 add more topology features and fixes/workarounds.
Patch 29 adds a helper to enable PCIe atomics to the PCI driver.
Patches 30-36 enable KFD initialization on dGPUs
Patch 37 enables KFD initialization on supported dGPUs in AMDGPU.

This is my last patch series this year. I worked hard to finish this
before my year-end vacation.
