6200c05e7d video: tegra: nvmap: Deprecate nvmap_ioctl_get_heap_size 
Remove function nvmap_ioctl_get_heap_size from nvmap, as the ioctl NVMAP_IOC_GET_HEAP_SIZE is being deprecated and its functionality is being replaced with NVMAP_IOC_QUERY_HEAP_PARAMS.

01db38f08e video: tegra: nvmap: Add support for Serial Id feature 
Add support for Serial Id feature which will be used by Nsight for
buffer tracking purpose. This feature expects a unique serial id per
buffer even if it is shared across multiple client processes.
Add following code:
- Create a new global counter field for serial id in nvmap device.
Initialize it to 0 when nvmap device is initialized.
- Introduce a new field for serial_id in nvmap_handle struct.
- When nvmap_handle is created, assign it's serial_id field with global
counter's value, and increment global counter.
- During NvRmMemQueryHandleParameters return this serial_id associated
with the handle.
- Do not decrement counter for serial_id even after freeing the handle.

30ebc1a639 video: tegra: nvmap: Add support for querying granule size 
Add support for querying the granule size using NvRmMemQueryHeapParams.
In case of compression carveout it returns granule size in which memory
is allocated while in case of IOVMM heap, it returns PAGE_SIZE.

594e39e498 video: tegra: nvmap: Add NUMA support in nvmap 
In NUMA system, user can request nvmap to allocate from any particular
node using NvRmMem APIs. Add code to request allocation from such
requested node. While allocating pages from page pool, check if those
pages belong to requested NUMA node. In some cases, we may not need to
use NUMA support e.g. in color pages allocation code, we don't need to
use NUMA, as page coloring is needed only for t19x chips.
