8c01fe4f87 drivers: pva: fix recovery 
When pva recovery is initiated due to command or
task submit timeout or initiated by pva-fw, queues
are cleared and tasks returned with error among other
cleanup activities and pva reset and fw reboot.

There could be multiple concurrent attempts to recover
the PVA engine.  Additionally, task and command submit
may be at varying stages of execution.

- Skip recovery requests while recovery work is pending.
- Skip task removal in case of timeout or invalidated task
  during task submit.
- Skip task submit to CCQ if task was removed during abort.
- Guard against concurrency during recovery
- Re-attempt pva reboot on fail during boot except in recovery.
- Reset driver PM state if module busy fails and PM error is set.
- Set default FW trace mask to WARN+ERROR+BOOT
- Set default driver log mask to FW TRACING
- ccq polling routine exits with timeout if abort is active

a3e0e896a0 tegra: nvmap: Fix nvmap_query_heap for multi numa node platform 
In current implementation, when NvRmMemQueryHeapParams is
called and multiple numa nodes are online:
1. For iovmm carveout, numa_id is set to garbage value,
   and we are calling compute_memory_stat with it.
2. For gpu carveout, we are returning values for
   numa_id 0.
3. For other carveouts, we are returning params for the
   first matching entry in nvmap_dev->heaps[i].

Correct this behavior as follows:
Regardless of carveout type, return params for numa_id 0
when NvRmMemQueryHeapParams is called and multiple numa
nodes are online.

In long-term, we need to disable NvRmMemQueryHeapParams
when multiple numa nodes are online. Clients should use
NvRmMemQueryHeapParamsNuma instead.

48e383a1b9 drm/tegra: Add option for explicit syncpoint free 
Add kernel module parameter to enable a mode where syncpoints
must be freed explicitly (using the free IOCTL) or they will be
left dangling. This ensures that, for particularly locked down
configurations, a syncpoint will be forever left in an expected
state even if the process owning it dies -- for example another
process will not be able to allocate it.

9feb2a4347 video: tegra: nvmap: Add multithreaded cache flush support 
On TOT, NvMap does page by page cache flush i.e. it takes virtual
address of each page present in the buffer and then perform cache
flush on it using dcache_by_line_op. This result in very poor
performance for larger buffers. ~70% of the time taken by
NvRmMemHandleAllocAttr is consumed in cache flush.
Address this perf issue using multithreaded cache flush
- Use a threshold value of 32768 pages which is derived from perf
experiments and as per discussion with cuda as per usecases.
- When the cache flush request of >= 32768 pages is made, then vmap
pages to map them in contiguous VA space and create n number of kernel
threads; where n indicate the number of online CPUs.
- Divide the above VA range among the threads and each thread would do
cache flush on the VA range assigned to it.

This logic in resulting into following % improvement for alloc tests.
