It's unchanged since the version I posted on March 24, with the exception that I've dropped the first patch, which was a testing-only patch. If there's no further comments I'll put this in a topic branch in the next day or two and Jiri & I will both merge that into next. cheers Michael Ellerman (5): ftrace: Make ftrace_location_range() global livepatch: Allow architectures to specify an alternate ftrace location powerpc/livepatch: Add livepatch header powerpc/livepatch: Add livepatch stack to struct thread_info powerpc/livepatch: Add live patching support on ppc64le arch/powerpc/Kconfig | 3 ++ arch/powerpc/include/asm/livepatch.h | 62 ++++++++++++++++++++++ arch/powerpc/include/asm/thread_info.h | 4 +- arch/powerpc/kernel/asm-offsets.c | 4 ++ arch/powerpc/kernel/entry_64.S | 97 ++++++++++++++++++++++++++++++++++ arch/powerpc/kernel/irq.c | 3 ++ arch/powerpc/kernel/process.c | 6 ++- arch/powerpc/kernel/setup_64.c | 17 +++--- include/linux/ftrace.h | 1 + kernel/livepatch/core.c | 34 ++++++++++-- kernel/trace/ftrace.c | 14 ++++- 11 files changed, 232 insertions(+), 13 deletions(-) create mode 100644 arch/powerpc/include/asm/livepatch.h -- 2.5.0
