Implement new API nvgpu_prof_ioctl_exec_reg_ops() to support regops on new profiler objects. Add two new staging buffers to hold regops copied from userspace, and to convert and execute regops in common code. Buffers are allocated and released along with the profiler object. New API will implements this : - copy regops data in chunks of 4K from userspace - store them in staging buffer - convert the new regop struct into common regop struct and also copy the content into second staging buffer - trigger gops.regops.exec_regops() with second staging buffer as operation pointer - convert common regop struct back into new regop struct and copy back to userspace Export bunch of helper functions from ioctl_dbg.h. e.g. nvgpu_get_regops_op_values_common() Update regop execution code to skip regop execution if regop status is not valid. This is only possible when userspace requests for CONTINUE_ON_ERROR mode. Add more documentation to some of the fields in UAPI header. Note that maximum atomic operations reported by new API are same as legacy API and are incorrect. This will be fixed up in upcoming patches.
