path.

6090a8a7ee gpu: nvgpu: move debugfs code to linux module
Since all debugfs code is Linux specific, remove
it from common code and move it to Linux module

Debugfs code is now divided into below
module specific files :

common/linux/debug.c
common/linux/debug_cde.c
common/linux/debug_ce.c
common/linux/debug_fifo.c
common/linux/debug_gr.c
common/linux/debug_mm.c
common/linux/debug_allocator.c
common/linux/debug_kmem.c
common/linux/debug_pmu.c
common/linux/debug_sched.c

Add corresponding header files for above modules too
And compile all of above files only if CONFIG_DEBUG_FS is set

Some more details of the changes made

- Move and rename gk20a/debug_gk20a.c to common/linux/debug.c
- Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h

- Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call
  gk20a_init_debug_ops() directly from gm20b_init_hal()

- Update all debug APIs to receive struct gk20a as parameter
  instead of receiving struct device pointer
- Update API gk20a_dmabuf_get_state() to receive struct gk20a
  pointer instead of struct device

- Include <nvgpu/debug.h> explicitly in all files where debug
  operations are used
- Remove "gk20a/platform_gk20a.h" include from HAL files
  which no longer need this include

- Add new API gk20a_debug_deinit() to deinitialize debugfs
  and call it from gk20a_remove()
- Move API gk20a_debug_dump_all_channel_status_ramfc() to
  gk20a/fifo_gk20a.c

2e338c77ea gpu: nvgpu: remove duplicate \n from log messages
nvgpu_log/info/warn/err() internally add a \n to the end of the message.
Hence, callers should not include a \n at the end of the message. Doing
so results in duplicate \n being printed, which ends up creating empty
log messages. Remove the duplicate \n from all err/warn messages.

ee25b33ca4 gpu: nvgpu: Proper timeout for NVGPU_COND_WAIT
The timeout parameter to NVGPU_COND_WAIT()
was passed directly to wait_event_timeout(), which takes jiffies.
Also allows zero timeout to disable timeout.

The return value of NVGPU_COND_WAIT() was defined in a way specific
to how Linux wait_event_() calls work. Replace that with proper error
reporting and change the callers to check against error codes.

b03afb6d5c gpu: nvgpu: add ioctls to get current timeslice
Add the following ioctls
- NVGPU_CHANNEL_IOCTL_GET_TIMESLICE for channel timeslice in us
- NVGPU_TSG_IOCTL_GET_TIMESLICE for TSG timeslice in us

If timeslice has not been set explicitly, ioctl returns the
default timeslice that will be used when programming the runlist
entry.

Replace the last of the Linux kmem API usage with nvgpu kmem
calls instead. Several places are left alone - allocating the
struct gk20a in particular.

Also one function was updated in the clk code to take a struct
gk20a as an argument so that it could use nvgpu_kmalloc().
