Thomas Zimmermann b1def7fadf drm/ast: Init iosys_map pointer as I/O memory for damage handling 
Ast hardware scans out the primary plane from video memory, which
is in I/O-memory space. Hence init the damage handler's iosys_map
pointer as I/O memory.

Not all platforms support accessing I/O memory as system memory,
although it's usually not a problem in ast's x86-based systems.

The error report is at [1].
