I noticed this in KMSG:

 tegra-mc 7000f000.memory-controller: overwriting group->as for swgroup: g2
 debugfs: File 'g2' in directory 'mappings' already present!
 tegra-mc 7000f000.memory-controller: overwriting group->as for swgroup: g2
 debugfs: File 'g2' in directory 'mappings' already present

Doesn't look okay, please fix.
