Merge tag 'trace-v4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt: "This fixes an issue with the build system caused by a change that modifies CC_FLAGS_FTRACE. The issue is that it breaks the dependencies and causes "make targz-pkg" to rebuild the entire world" * tag 'trace-v4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/Makefile: Fix handling redefinition of CC_FLAGS_FTRACE
