Linus Torvalds 10f4902173 Two more tracing fixes 
- Have kprobes not use copy_from_user() to access kernel addresses,
    because kprobes can legitimately poke at bad kernel memory, which
    will fault. Copy from user code should never fault in kernel space.
    Using probe_mem_read() can handle kernel address space faulting.
 
  - Put back the entries counter in the tracing output that was accidentally
    removed.
