e445b57b04 gpu: nvgpu: Move interrupt ISR code to common 
This is one of the steps in restructuring of interrupt code.
- Move ISR logic to common code. This will allow us to add mixed ASIL
error handling levels.
- Modify nonstall ISR to use threaded interrupts. Bottom half of
nonstall ISR will run nonstall operations instead of adding work to
workqueues.
- Remove nonstall workqueue implementation.

f41e5975d8 gpu: nvgpu: add ioctl to configure l2 max_ways_evict_last 
Add ioctl support to configure and read the max number of lines/ways
in a L2 cache set that can be marked as EVICT_LAST. This is accomplished
through two new ltc hals: set_l2_max_ways_evict_last,
get_l2_max_ways_evict_last. These hals will only be set for nvgpu-next
chips. Incase of legacy chips, the IOCTLs will return error -ENOSYS.

Generate following litter constants to get the number of sets in a l2
slice and the number of ways in each set:
- GPU_LIT_NUM_LTC_LTS_SETS
- GPU_LIT_NUM_LTC_LTS_WAYS

Add gpu characteritics flag: NVGPU_L2_MAX_WAYS_EVICT_LAST_ENABLED to
allow userspace driver to determine if L2_MAX_WAYS_EVICT_LAST ioctl is
supported.

77c0b9ffdc gpu: nvgpu: Update runlist_update() to take runlist ptr 
Update the nvgpu_runlist_update_for_channel() function:

  - Rename it to nvgpu_runlist_update()
  - Have it take a pointer to the runlist to update instead
    of a runlist ID. For the most part this makes the code
    better but there's a few places where it's worse (for
    now).

This starts the slow and painful process of moving away from
the non-runlist code using runlist IDs in many places it should
not.

Most of this patch is just fixing compilation problems with
the minor header updates.

456a814db5 gpu: nvgpu: add linux MAPPING_MODIFY ioctl 
Add new MAPPING_MODIFY ioctl to the linux nvgpu driver.

This ioctl is used (for example) by the NvRmGpuMappingModify API to
change the kind of an existing mapping.

For compressed mappings the ioctl can be used to do the following:

 * switch between two different compressed kinds
 * switch between compressed and incompressed kinds

For incompressed mappings the ioctl can be used to do the following:

 * switch between two different incompressed kinds

In order to properly update an existing mapping the nvgpu_mapped_buf
structure has been extended to cache the following state when the
mapping is first created:

 * the compression tag offset (if applicable)
 * the GMMU read/write flags
 * the memory aperture

The unused ctag_lines field in the nvgpu_ctag_buffer_info structure
has been replaced with a new ctag_offset field.

Also rename the fields runlist_info and active_runlist_info to
simply runlists and active_runlists respectively. Again the info
text is just not necessary and somewhat misleading. These structs
_are_ the runlist representations in SW; they are not merely
informational.

Also add an rl_dbg() macro to print debug info specific to
runlist management and some debug prints specifying the runlist
topology for the running chip.

cf287a4ef5 gpu: nvgpu: retry tsg unbind if NEXT is set 
The NEXT bit can remain set for the channel if timeslice expires before
scheduler clears it. Due to this nvgpu fails TSG unbind and in turn
nvrm_gpu fails channel close. In this case, checking the channel hw
state after some time can help see NEXT bit cleared by scheduler.

Reenable the tsg and return -EAGAIN to nvrm_gpu for it to retry again.

cae88e7451 gpu: nvgpu: initialize cau data while binding HWPM in global mode 
Add CAU initialization data in const array hwpm_cau_init_data[].
Add HAL API gops.gr.get_hwpm_cau_init_data() to retrieve this data
and implement it for TU104.

Add new HAL API gops.gr.init_cau() that uses above data and
initializes all cau units. Implement this HAL only for TU104.

Invoke above sequence from nvgpu_profiler_bind_hwpm() in case of
global HWPM mode.
