The drm_mm debugfs output is difficult to read as two different formats are used for the addresses:
0x00000080000000-0x0000008000b000: 45056: used 0x8000b000-0x80016000: 45056: free 0x00000080016000-0x0000008001b000: 20480: used 0x8001b000-0x817a1000: 24666112: free 0x000000817a1000-0x000000817a8000: 28672: used 0x000000817a8000-0x00000081ba8000: 4194304: used
Fix this by using %#018llx for all addresses, thus making the output:
0x0000000080000000-0x000000008000b000: 45056: used 0x000000008000b000-0x0000000080016000: 45056: free 0x0000000080016000-0x000000008001b000: 20480: used 0x000000008001b000-0x00000000817a1000: 24666112: free 0x00000000817a1000-0x00000000817a8000: 28672: used 0x00000000817a8000-0x0000000081ba8000: 4194304: used

Please apply this patch; I didn't see the need to create a new branch just for one patch. Thanks.
