      ftrace: handle archs that do not support irqs_disabled_flags · 9244489a

      Impact: build fix on non-lockdep architectures
      
      Some architectures do not support a way to read the irq flags that
      is set from "local_irq_save(flags)" to determine if interrupts were
      disabled or enabled. Ftrace uses this information to display to the user
      if the trace occurred with interrupts enabled or disabled.
      
      Besides the fact that those archs that do not support this will fail to
      compile, unless they fix it, we do not want to have the trace simply
      say interrupts were not disabled or they were enabled, without knowing
      the real answer.
      
      This patch adds a 'X' in the output to let the user know that the
      architecture they are running on does not support a way for the tracer
      to determine if interrupts were enabled or disabled. It also lets those
      same archs compile with tracing enabled.

      ftrace: fix trace_nop config select · f3384b28

      Impact: build fix on non-function-tracing architectures
      
      The trace_nop is the tracer that is defined when no tracer is set in
      the ftrace infrastructure.
      
      The trace_nop was mistakenly selected by HAVE_FTRACE due to the confusion
      between ftrace infrastructure and the ftrace function tracer (which has
      been solved by renaming the function tracer).
      
      This patch changes the select to the approriate TRACING.
      
      This patch should fix compile errors on architectures that do not define
      the FUNCTION_TRACER.
