Try to allocate system memory on the NUMA node the device is closest to and try to run delayed_delete workers on a CPU of this node as well. To optimize the memory clearing operation when a TTM BO gets freed by the delayed_delete worker, scheduling it closer to a NUMA node where the memory was initially allocated helps avoid the cases where the worker gets randomly scheduled on the CPU cores that are across interconnect boundaries such as xGMI, PCIe etc. This change helps USWC GTT allocations on NUMA systems (dGPU) and AMD APU platforms such as GFXIP9.4.3.
