Converted some of the pr_debug()s to tracepoints - this is partly a performance optimization; it used to be that with DEBUG or CONFIG_DYNAMIC_DEBUG pr_debug() was an empty macro; but at some point it was changed to an empty inline function. Some of the pr_debug() statements had rather expensive function calls as part of the arguments, so this code was getting run unnecessarily even on non debug kernels - in some fast paths, too.
