Thomas Gleixner ff5c4f5cad rcu/tree: Mark the idle relevant functions noinstr
These functions are invoked from context tracking and other places in the
low level entry code. Move them into the .noinstr.text section to exclude
them from instrumentation.

Mark the places which are safe to invoke traceable functions with
instrumentation_begin/end() so objtool won't complain.
