+Subject: [PATCH 0862/4131] drm/amdgpu: track evicted page tables v2
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Instead of validating all page tables when one was evicted,
+track which one needs a validation.
+
+v2: simplify amdgpu_vm_ready as well
+
