Hi Dave & Daniel,

Bit late PR due to Easter break. 

Prep work for local memory support as requested. Hard hang
fix for Sandybridge. Sanitize dma-buf size on import and
avoid GPU reset if heartbeat callback runs before timeout.

The rest is mostly small fixes and code/checkpatch cleanups.

Regards, Joonas
