STill the same Oops, below
Unfortunately, I don't have a PPC machine (32 nor 64 bit) to help debug
this.
I will look more closely tomorrow.
OK, thanks.
The Oops was due to ftrace_caller() setting the regs argument to NULL.
After fixing that, I'm back into a situation where I get "Testing tracer function_graph: FAILED!"
Will continue investigating.
