From 23bf70ad8e4d5a722475c6e06f289c625dfa4b7c Mon Sep 17 00:00:00 2001

Subject: [PATCH 3049/4131] drm/amdkfd: Delete an useless call of
kfd_flush_tlb()
During process creation, no vmid is associated with the process for both
HWS and non-HWS case, because no queues have been created. So a TLB
flush doesn't make sense.
