6c2c4181ae gpu: nvgpu: Create hal.mm.mm for misc MM HALs
There are many miscellaneous HALs for various MM related functionality.
This patch aims to migrate all the remaining MM code from the <chip>/
mm_<chip>.[ch] files in HAL files under hal/.

Much of this is fairly straightforward copy/paste and updates to the
HAL init files.

The exception to that is the move of the left over gv11b MMU fault
handling code in mm_gv11b.c. Having both a hal/mm/mm/mm_gv11b.c and
a gv11b/mm_gv11b.c file causes tmake to choke so the gv11b/mm_gv11b.c
file was moved to gv11b/mmu_fault_gv11b.c. This will be cleaned up in
a subsequent patch.

1533951567 gpu: nvgpu: move cyclestats_snapshot data to struct gk20a
cyclestats_snapshot data and lock is right now stored in struct nvgpu_gr
Use case itself is not specific to GR engine but in general it applies
to other units outside of GR too.

Hence it makes sense to move both data and lock to struct gk20a instead
of keeping them in struct nvgpu_gr

Update all cyclestats_snapshot code to refer data/lock from struct gk20a
Remove gr_priv.h header include from cyclestats_snapshot.c

Some of the functions were mistakenly declared in gr_gk20a.h.
Move them to cyclestats_snapshot.h and rename them to form nvgpu_css_*()

f8b3d50360 gpu: nvgpu: remove gr_gk20a.ctx_vars struct
gr_gk20a.ctx_vars struct right now stores sizes for golden_image, zcull,
pm_ctxsw, and gfxp_preemption_buffer.
but these sizes should be really owned by respective units and should
be assigned to units as soon as they are queried from FECS

Add new structure to nvgpu_gr_falcon to hold sizes that will be queried
from FECS
struct nvgpu_gr_falcon_query_sizes {
        u32 golden_image_size;
        u32 pm_ctxsw_image_size;
        u32 preempt_image_size;
        u32 zcull_image_size;
};

gr.falcon unit now queries sizes from FECS and fills this structure.
gr.falcon unit also exposes below APIs to query above sizes

u32 nvgpu_gr_falcon_get_golden_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_pm_ctxsw_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_preempt_image_size(struct nvgpu_gr_falcon *falcon);
u32 nvgpu_gr_falcon_get_zcull_image_size(struct nvgpu_gr_falcon *falcon);

gr.gr unit now calls into gr.falcon unit to initailize sizes, and then
uses above exposed APIs to set sizes into respective units

vGPU will too fill up struct nvgpu_gr_falcon_query_sizes with all the sizes
and then above APIs will be used to set sizes into respective units

All of above means size variables in gr_gk20a.ctx_vars struct are no more
being referred. Delete them.

gfxp_wfi_timeout_count/unit fields were stored in gr_gk20a.ctx_vars
struct so that any user could configure them through sysfs nodes

But the sysfs nodes are legacy and not being actively used by anyone.
Hence delete the sysfs nodes to configure these fields.

Since the gfxp timeout unit/count can now be statically programmed,
make following changes
- remove g->ops.gr.init_gfxp_wfi_timeout_count() hal
- remove g->ops.gr.get_max_gfxp_wfi_timeout_count() hal
- update g->ops.gr.init.preemption_state() hals to configure the values
  using macros instead of caller passing the values
- update g->ops.gr.init.gfxp_wfi_timeout() hals to configure the values
  using macros instead of caller passing the values

Finally, we don't need to store gfxp_wfi_timeout_count/unit fields
anymore, hence delete them from gr_gk20a.ctx_vars

77140c1a84 gpu: nvgpu: move dump_ctxsw_stats_on_channel_close flag to gr_ctx_desc
Debug boolean flag dump_ctxsw_stats_on_channel_close is right now stored
in gr_gk20a.ctx_vars struct
This flag logically is property of gr.ctx units since it indicates
whether each context should dump ctxsw stats on channel/context close

Move this flag to struct nvgpu_gr_ctx_desc and remove it from
gr_gk20a.ctx_vars

Expose below API from gr.ctx unit to check if flag is set
nvgpu_gr_ctx_desc_dump_ctxsw_stats_on_channel_close()

Move debugfs creation code to create corresponding debugfs to
gr_gk20a_debugfs_init() and change debugfs type from "u32" to "file"

Struct gr.gr_ctx_desc is created only during first poweron.
Return error if this struct is not available.

Remove unnecessary initialization of this variable from platform
specific probe functions
