Add these bits in the gpu characteristics flags:
NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING - fast
submits with no in-kernel job tracking are supported.
NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL - deterministic
submits also with job tracking and num_inflight_jobs set are supported.
Either of these may get disabled if the particular channel or submit
still requires features that block these.
Make gk20a_channel_sync_needs_sync_framework() take a gk20a pointer
instead of a channel pointer so that it can be called without a channel.
It does not need any per-channel data.

then when including bitops.h we get both bitmap declarations and bit
ops declarations.

Use an nvgpu_mem created from a page in the ACR code instead of
a scatter gather table created by the Linux SGT APIs. The ACR code
needs to have the GPU map a physical page queried from an external
API (other than the regular DMA API).
Note that this code used to explicitly mark the SGT it makes as
bypassing the SMMU. However, that is now taken care of implicitly
by the __nvgpu_mem_create_from_pages() function.

The gfp_t argument for dma_alloc_attrs() cannot take DMA_MEMORY_NOMAP -
it's interpreted as __GFP_RECLAIMABLE which has the same integer value.
Use GFP_KERNEL for the flag argument and set DMA_ATTR_NO_KERNEL_MAPPING
for dma attrs which the code was trying to do with the flag that is
meant for the coherent allocation API.

nvgpu is being modularized for kernel-4.4 and newer kernels.
__alloc_fd() can't be used on modules as it is not exported.
So, use a wrapper tegra_fd_alloc() instead of __alloc_fd()

Use struct nvgpu_mem for DMA allocations (and the corresponding
nvgpu_dma_alloc_sys()) instead of custom rolled code. This migrates
away from using linux scatter gather tables directly. Instead this
is hidden in the nvgpu_mem struct. With this change the semaphore.c
code no longer has any direct Linux dependencies.

Add a function to create a nvgpu_mem from a list of arbitrary pages.
This API is useful for pages not necessarily allocated by the Linux
page allocator. It is useful for making nvgpu_mems that represent
carveouts or other things like that.

Move and rename the functions that build sgtables for nvgpu_mems into
the Linux specific DMA code.
One place outside of the Linux code do include the Linux DMA header.
That will be fixed in a subsequent patch.

Add an API for creating a special sub-nvgpu_mem struct. This struct
comes with some fairly important caveats but is very useful for the
semaphore code.
Also, make sure that in nvgpu_mem_begin() and nvgpu_mem_end() no
additional mappings are made if not necessary. More importantly during
nvgpu_mem_end() it would be possible to vunmap() a CPU mapping of a
DMA allocation that does not expect this to happen.

Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This
includes some functions in allocators that were used only for
debugging.
Remove include of linux/debugfs.h on files that do not deal with
debugfs.
linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.
