[ Upstream commit bbdf514fe5648566b0754476cbcb92ac3422dde2 ]

dGPUs need their own topology devices. Don't assign them to APU topology
devices with CPU cores.

[ Upstream commit 2383a767c0ca06f96534456d8313909017c6c8d0 ]

Vega10 has multiple interrupt rings, so this can be called from multiple
calles at the same time resulting in:

[   71.779334] ================================

Fix this by always using irq save spin locks.

This mm_struct pointer should never be dereferenced. If running in
a user thread, just use current-&gt;mm. If running in a kernel worker
use get_task_mm to get a safe reference to the mm_struct.

Firmware have the workaround to replace the atomic Ops with read-modify-write on CP side.
User should not expect atomic Ops on system memory works normally if system didn't not
support it.
