Subject: [PATCH 1/2] Revert "drm/amdkfd: flush TLB after updating GPU page table"
Date: Thu, 13 May 2021 12:58:54 -0400	[thread overview]
Message-ID: <20210513165855.16395-1-Philip.Yang@amd.com> (raw)

This reverts commit bcbc99676607d4ff9fd15f27481cb1794a567d65.

After "drm/amdgpu: flush TLB if valid PDE turns into PTE" is checked
in, this workaround is not needed.
