Subject: ftrace: annotate core code that should not be traced
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6e766410c4babd37bc7cd5e25009c179781742c8;p=linux-beck.git

ftrace: annotate core code that should not be traced

Mark with "notrace" functions in core code that should not be
traced.  The "notrace" attribute will prevent gcc from adding
a call to ftrace on the annotated funtions.
