0188b93e30 gpu: nvgpu: move gk20a_fifo_recover_tsg into tsg unit
gk20a_fifo_recover_tsg does high-level software calls and
invokes gk20a_fifo_recover. This function belongs to the tsg unit and
is moved to tsg.c file. Also, the function is renamed to
nvgpu_tsg_recover.

7e68e5c83d gpu: nvgpu: userd slab allocator
We had to force allocation of physically contiguous memory for
USERD in nvlink case, as a channel's USERD address is computed as
an offset from fifo->userd address, and nvlink bypasses SMMU.

With 4096 channels, it can become difficult to allocate 2MB of
physically contiguous sysmem for USERD on a busy system.

PBDMA does not require any sort of packing or contiguous USERD
allocation, as each channel has a direct pointer to that channel's
512B USERD region. When BAR1 is supported we only need the GPU VAs
to be contiguous, to setup the BAR1 inst block.

- Add slab allocator for USERD.
- Slabs are allocated in SYSMEM, using PAGE_SIZE for slab size.
- Contiguous channels share the same page (16 channels per slab).
- ch->userd_mem points to related nvgpu_mem descriptor
- ch->userd_offset is the offset from the beginning of the slab

- Pre-allocate GPU VAs for the whole BAR1
- Add g->ops.mm.bar1_map() method
  - gk20a_mm_bar1_map() uses fixed mapping in BAR1 region
  - vgpu_mm_bar1_map() passes the offset in TEGRA_VGPU_CMD_MAP_BAR1
  - TEGRA_VGPU_CMD_MAP_BAR1 is called for each slab.

303fc7496c gpu: nvgpu: common: fix MISRA Rule 10.4 Violations
MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.

Adding "U" at the end of the integer literals or casting operands
to have same type of operands when an arithmetic operation is
performed.

This fixes violations where an arithmetic operation is performed on
signed and unsigned int types.

fc939e5fb6 gpu: nvgpu: Add IOCTL flag + plumbing for unified VAs
Add a flag that let's userspace enable the unified VM functionality
on a selective bassis. This feature is working for all cases except
a single MODS trace. This will allow test coverage to be selectively
added in certain userspace tests as well to help prevent this feature
from bit rotting (as it has historically done).

Also update the unit test for the page table management in the GMMU
to reflect this new flag. It's been set to false since the target
platform for safety is currently not using unified address spaces.

so this patch moves all the pd_cache specifics over to a new
header file: <nvgpu/pd_cache.h>.

Also a couple of static inlines that were possible when the code

This allowed the pd_cache.h header to not include the gmmu.h

Also fix an issue in the nvgpu_pd_write() function where the data
was being passed as a size_t for some reason. This has now been
changed to a u32.

All the 16.x MISRA rules are relevant to switch statement
formatting and hence addressed in single patch

As per MISRA 16.1, all switch statements should be well formatted.

16.3 fixes:
Add unconditional break statements to all the switch-clauses
to adhere to MISRA rule 16.3. Also do not allow fall-through
(even the intentional ones) from one switch-clause to next one.

16.4 fixes:
Make sure all "default" clauses in the switch statements are
non-empty.

16.6 fixes:
Fix all switch statement formatting to fix MISRA 16.6 violations
which requires all the switch clauses to be conforming.
