Instead of current preallocated array plus dynamically allocated
temporary contexts, use a linked list in LRU fashion, always storing
free contexts at the beginning of the list. Initialize the preallocated
contexts to the list and store dynamically allocated temporaries there
too for quick reuse as needed, with a delayed scheduled work for
deleting temporaries when the high load has diminished.

Since the number of TPCs is different between GM20B and GK20a,
the function to look up the number of TPCs needs to be halified.

gk20a_get_client() and gk20a_put_client() routines are effectively dead
code. The GPU has been using pm_runtime for reference counting whether
the device should be turned on or off, and gk20a_get_client() and
gk20a_put_client() have had no positive effect on the behaviour.
In worst case these functions trigger some issues as they may trigger
code paths that should not be run. There is also a race between get/put
and busy/idle.
This patch removes the functions and reworks as_gk20a.c to correctly use
gk20a_busy()/gk20a_idle() where put/get was required.
Additionally, finalize_poweron() is moved to gk20a_busy(), similarly as
it was with gk20a_get_client(). If pm_runtime is not in use, the device
is only powered on and never off. Currently this affects vgpu power
management since it does not use pm_runtime yet.

Implement support for 64kB large page size. Add an API to create an
address space via IOCTL so that we can accept flags, and assign one
flag for enabling 64kB large page size.
Also adds APIs to set per-context large page size. This is possible
only on Maxwell, so return error if caller tries to set large page
size on Kepler.
Default large page size is still 128kB.

GK20A PMU is not supported in GPU client for virtualization. However,
to make native case and virtualization case can share same defconfig and
kernel image, we need to enable CONFIG_GK20A_PMU and
CONFIG_GK20A_DEVFREQ in defconfig. This commit changes to detect if we
should disable GK20A PMU support in run time.

In this case, we follow below sequence :

- call prepare_poweroff() to save the state explicitly
- perform explicit reset assert/deassert
- call finalize_poweron() to restore the state
- drop the runtime reference taken earlier

Add explict memory barrier wmb() before writing to register values.
Also call writel_relaxed() instead of writel() to skip internal
wmb() call which is conditional on some configs.

- Add a sysfs "force_idle" to forcibly idle the GPU
- read on this sysfs will return the current status
0 : not in idle (running)

"echo 1 > force_idle" will force the gpu into idle
"echo 0 > force_idle" will cause the gpu to resume

- take read lock on busy_lock inside gk20a_busy()
so that all usual requests can execute simultaneously
- write lock can be taken when we need to block all
