o QoS notifier
Refresh the gpu load query because we may update the emc target
if gpu load changed.
o tegra_postscale()
Scaling the emc clock to a new target may be necessary
if the gpu load changed at low gpu frequencies.

The current CUDA drivers have been using the regops to
directly accessing the GPU registers from user space through
the dbg node. This is a security hole and needs to be avoided.
The patch alternatively implements the similar functionality
in the kernel and provide an ioctl for it.

Timestamps read in an interrupt handler and when fence state

add unnecessary jitter to original interrupt times.
This patch adds support for passing timestamp from the device

Add "force_reset" flag to __gk20a_do_idle()
For real world use cases like VPR resizing, we cannot wait
for railgate_delay (which is 500 mS). Hence use CAR reset
for this use case. (this is done via gk20a_do_idle() API
with force_reset = true)
Some of the test cases make use of sysfs "force_idle" and
they expect GPU to be into really railgated state and
not in CAR reset.
Hence when called from sysfs, set force_reset = false.
When global flag "force_reset_in_do_idle" is set, it will
override local flags and force CAR reset case.
This is desired in cases where railgating is not enabled
Also, set force_reset_in_do_idle = false for GM20B since
railgating has been enabled for GM20B

Call validate_reg_ops() even when allow_all is set, since that function
takes care of counting ctxsw regops which would not be executed without
the counters set.

Dump GR status registers in case of ctxsw timeout.
This is helpful in case where ctxsw timeout is encountered
during stress testing but we lose the bad state since we do
the recovery. So dump as much status as we can when timeouts
are seen
