I modified these a little from the last postings. 1) I removed the changes to recordmcount.pl. This is not a PowerPC change, although PowerPC needs it for dynamic ftrace. But the changes here can go via linux-tip. 2) I removed the adding of HAVE_DYNAMIC_FTRACE and HAVE_FTRACE_MCOUNT_RECORD. Without these config options, this code will not be compiled. I have a separate patch that adds them in when the time is right. Paul, these patches should not harm anything if you decide to pull them in. As I stated above, without the above config options, they are not enabled. There is one exception and that is for the first patch. The first patch is actually a fix for the irqsoff latency tracer which is already in mainline for PowerPC. These patches only touch PowerPC code. The following patches are in: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git branch: ppc/ftrace Steven Rostedt (5): powerpc: ftrace, do not latency trace idle powerpc: ftrace, convert to new dynamic ftrace arch API powerpc: ftrace, use probe_kernel API to modify code powerpc/ppc64: ftrace, handle module trampolines for dyn ftrace powerpc/ppc32: ftrace, dynamic ftrace to handle modules ---- arch/powerpc/include/asm/ftrace.h | 14 +- arch/powerpc/include/asm/module.h | 16 ++- arch/powerpc/kernel/ftrace.c | 473 +++++++++++++++++++++++++++++++++--- arch/powerpc/kernel/idle.c | 5 + arch/powerpc/kernel/module_32.c | 10 + arch/powerpc/kernel/module_64.c | 13 + 6 files changed, 489 insertions(+), 42 deletions(-)
