Update extended buffer definition for Maxwell. On GM20B only PERF_CONTROL0 and
PERF_CONTROL5 registers are restored in extended buffer. They are needed for
stopping the counters as late as possible during ctx save and start them as
early as possible during context restore. On Maxwell, these registers contain
the enable/disable bit.

o emc clock scaling
Only take the gpu load into account for gpu frequencies below
fmax @ Vmin.
The granularity of frequency steps is much larger in the gpu
frequency range below fmax @ Vmin than in the upper frequency range.
Above fmax @ Vmin, keep the gpu unblocked and disregard the gpu load
when evaluating the emc target.
o tegra_postscale()
Round the new emc target to nearest discrete frequency.
Set the emc frequency only if the new emc target is different
from the previously requested emc frequency to avoid the penalty
of the locks inside clk_set_rate().

Move the fifo engine activity disabling and wait-for-idle from the
lowest-level functions higher, into the ioctl path of zbc operations, so
that the sw initialization path wouldn't call them. During the init
path, the disable isn't necessary, and the code path could result in a
deadlock in the fifo runlist mutex.

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

Below check assumes that available syncpt range
starts from 0
id >= nvhost_syncpt_nb_pts_ext()
Instead of using this API, use nvhost_syncpt_is_valid_pt_ext()
which validates the syncpt id against both upper and lower
boundaries

Add a big mutex for protecting the channel during ioctls, in case the
userspace uses the same channel from several threads at once. The lock
is taken during all operations except CHANNEL_WAIT, which could deadlock.

Pass always the directory structure to mm functions instead of
pointers to members to it. Also split update_gmmu_ptes_locked()
into smaller functions, and turn the hard
coded MMU levels (PDE, PTE) into run-time parameters.

CUDA devtools need to be able to flush the GPU's cache
in a sideband fashion and so cannot use methods. This
change implements an nvgpu_gpu_ioctl to flush and
optionally invalidate the GPU's L2 cache and flush fb.
