This reverts commit 1addc1264852 This commit seems to cause crashes in gk104_fifo_intr_runlist() by returning 0xbad0da00 when register 0x2a00 is read. Since this commit was intended for GM20B which is not completely supported yet, let's revert it for the time being.

This addresses two issues that cause problems with viewperf maya-03 in situation with memory pressure. The first issue causes attempts to unreserve buffers if batched reservation fails due to, for example, a signal pending. While previously the ttm_eu api was resistant against this type of error, it is no longer and the lockdep code will complain about attempting to unreserve buffers that are not reserved. The issue is resolved by avoid calling ttm_eu_backoff_reservation in the buffer reserve error path. The second issue is that the binding_mutex may be held when user-space fence objects are created and hence during memory reclaims. This may cause recursive attempts to grab the binding mutex. The issue is resolved by not holding the binding mutex across fence creation and submission.

Once pm_runtime_set_active() gets called, the kernel assumes that given device has already enabled runtime pm and will call pm_runtime_suspend() without matching pm_runtime_resume(). In case of DRM FIMC IPP driver, this will result in calling clk_disable() without respective call to clk_enable(). This patch removes call to pm_runtime_set_active() to ensure that pm_runtime_suspend/resume calls will match.
