- Remove the usage of nvgpu_ctxsw_trace_entry splattered across nvgpu, and replace with a struct defined in common code. The usage is still inside Linux, but this helps the subsequent unification efforts, e.g. to unify the fecs trace path. - Remove "asm/barrier.h" as "nvgpu/barrier.h" is already included.
