I'm not using anything :)
This is about the tracing_cpumask debugfs file implemented in trace.c
It's tracing_cpumask_write function uses the raw_local functions, I
guess because its locking doesn't need to be traced.
And the problem here is that some archs don't implement raw_local
functions and so trace.c doesn't compile with alpha or m68k.
But actually this file is not needed for them.
