Changes in v2:
- Prepare arm_smu_flush_ops for override.
- Remove NVIDIA_SMMUv2 and use ARM_SMMUv2 model as T194 SMMU hasn't modified
ARM MMU-500.
- Add T194 specific compatible string - "nvidia,tegra194-smmu"
- Remove tlb_sync hook added in v1 and Override arm_smmu_flush_ops->tlb_sync()
from imp
Add binding for NVIDIA's Tegra194 Soc SMMU that is based
on ARM MMU-500.

I have split this work into 3 simple patches, so the code is straight
forward to review and so that if any mistakes slip in it is easy to
bisect them. In the process of review what it takes to remove
task_rcu_dereference I found yet another user of tasks on the
runqueue in rcu context; the rcuwa
Add a count of the number of rcu users (currently 1) of the task
struct so that we can later add the scheduler case and get rid of the
very subtle task_rcu_dereference, and just use rcu_dereference.
As suggested by Oleg have the count overlap rcu_head so that no
additional space in task_struct i
In the ordinary case today the rcu grace period of a task comes when a
task is reaped, well after the task has left the runqueue. This
change guarantees that the rcu grace period always happens after a
task has left the runqueue. As this is something that usaually happens
today I do not expect
Use rcu_dereference instead of task_rcu_dereference.
Remove task_rcu_dereference.
Remove the complications of rcuwait that were in place because tasks
on the runqueue were not rcu protected. It is now safe to call
wake_up_process if the target was know to be on the runqueue in the
current rcu

With the underscore character in the lsm9ds1_imu device name, we get the
following error below, so use a dash, just like the other device names do too.
