* gpu: nvgpu: Add timeout to L2 flushAlex Waterman2015-03-18
| | | | | | | | | | | | Add a timeout mechanism to the L2 flushing code for gm20b. Previously the code could spin forever in a loop if some issue were to occur with the L2 causing the flush to fail.

* gpu: nvgpu: gm20b: fix compression sharingKevin Huang2015-03-18
| | | | | | | | | | | | | | | | For GM20B alone, the LTC count is already accounted for the HW logic for the CBC base calculation from the postDivide address. So SW doesn't have to explicity divide it by the LTC count in the postDivide address calculation.
