It was actually suppose to go into the 4.6 merge window, but I never committed it. I almost forgot about it again, but noticed it was missing from your tree. - Soumya PN sent me a clean up patch to not disable interrupts when taking the tasklist_lock for read, as it's unnecessary because that lock is never taken for write in irq context. - Newer gcc's can cause the jump in the function_graph code to the global ftrace_stub label to be a short jump instead of a long one. As that jump is dynamically converted to jump to the trace code to do function graph tracing, and that conversion expects a long jump it can corrupt the ftrace_stub itself (it's directly after that call). One way to prevent gcc from using a short jump is to declare the ftrace_stub as a weak function, which we do here to keep gcc from optimizing too much" * tag 'trace-v4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace/x86: Set ftrace_stub to weak to prevent gcc from using short jumps to it ftrace: Don't disable irqs when taking the tasklist_lock read_lock ftracetest: Add instance created, delete, read and enable event test # < /opt/cross/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 7639dad93a5564579987abded4ec05e3db13659d # < make -j 48 ARCH=arm O=/home/kisskb/slave/build/linus_realview-smp_defconfig_arm CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- realview-smp_defconfig make[2]: *** [realview-smp_defconfig] Error 1 make[1]: *** [realview-smp_defconfig] Error 2 make: *** [sub-make] Error 2 Command 'make -j 48 ARCH=arm O=/home/kisskb/slave/build/linus_realview-smp_defconfig_arm CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- realview-smp_defconfig' returned non-zero exit status 2 # rm -rf /home/kisskb/slave/build/linus_realview-smp_defconfig_arm # Build took: 0:00:02.440843
