We right now define HAL exec_reg_ops() under gops.dbg_session_ops operations
But we have separate gops.regops operations for all the regops and this would
be logically correct place for exec_reg_ops()
Move exec_reg_ops() from gops.dbg_session_ops to gops.regops
Also rename it to exec_regops()

The error returned from the execution of exec_reg_ops was ignored
leading to not propagating the error values to the caller methods.
This patch handles the error occurence in the exec_reg_ops call.

Add new ioctl to set the SM_EXCEPTION_TYPE_MASK is
added to dbg session.
Currently support SM_EXCEPTION_TYPE_MASK_FATAL type
If this type is set then the code will skip RC recovery,
instead trigger CILP preemption.

In nvgpu_ioctl_channel_reg_ops(), we right now first check if context is
allocated or not and if context is not allocated we fail the regops operation
But it is possible that the regops operation only includes global regops which
does not need global context allocated
So move this global context check from nvgpu_ioctl_channel_reg_ops() to
exec_regops_gk20a() and only if we have context ops included in the regops

For IOCTL NVGPU_DBG_GPU_IOCTL_ACCESS_FB_MEMORY, we do not allow size of buffer
which is not 4 byte aligned
Remove this hard restriction and allow non 4 byte aligned buffer sizes too
since we don't really need to enforce this restriction

- Write new pm mode to context buffer header. Ucode use
this mode to enable mode-e context switch. This is Mode-B
context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.

Rename os/linux/vidmem.c to os/linux/dmabuf_vidmem.c. The code is
mainly dealing with interfacing with Linux dmabuf framework and its
responsibilities got confused with common/mm/vidmem.c.
Also move the header include/nvgpu/linux/vidmem.h to
os/linux/dmabuf_vidmem.h. It does not expose any interface to outside
Linux code.

Update the Linux specific code to match the MM API docs in the
previous patch. The user passed page size is plumbed through
the Linux VM mapping calls but is ultimately ignored once the
core VM code is called. This will be handled in the next
patch.
This also adds some code to make the CDE page size picking
happen semi-intelligently. In many cases the CDE buffers can
be mapped with large pages.

Moved PG refcount checking to a wrapper function, this
function manages the refcount and decides whether to call
dbg_set_powergate function.
Instead of checking the dbg_s->is_pg_disabled variable,
code is checking g->dbg_powergating_disabled_refcount
variable to know if powergate is disabled or not.
Updating hwpm ctxsw mode without disabling powergate
will result in priv errors.
