Thus, the sparc, arm and tile patch have been added to address this issue. In addition, an 'allyesconfig' on arm did not build either due to the usage of -O0 compiler flag. This has been removed in this patch: http://lkml.iu.edu/hypermail/linux/kernel/1606.3/01587.html So this series depends on that patch to build properly on arm (which I currently see being pulled into linux-next). -v3: *added sparc, arm, tile patches for cross section references *re-based on (4c5ea0a locking/static_key: Fix concurrent static_key_slow_inc()) Thanks, -Jason Chris Metcalf (1): tile: support static_key usage in non-module __exit sections Jason Baron (6): powerpc: add explicit #include for jump label s390: add explicit #include for jump label sparc: support static_key usage in non-module __exit sections arm: jump label may reference text in __exit jump_label: remove bug.h, atomic.h dependencies for HAVE_JUMP_LABEL dynamic_debug: add jump label support arch/arm/kernel/vmlinux.lds.S | 2 +- arch/powerpc/include/asm/jump_label.h | 1 + arch/s390/include/asm/jump_label.h | 1 + arch/sparc/kernel/vmlinux.lds.S | 7 ++++ arch/tile/kernel/vmlinux.lds.S | 12 +++++++ include/linux/dynamic_debug.h | 60 +++++++++++++++++++++++++++++++---- include/linux/jump_label.h | 46 +++++++++++++-------------- kernel/jump_label.c | 53 +++++++++++++++++++++++++++++++ lib/dynamic_debug.c | 7 ++++ 9 files changed, 159 insertions(+), 30 deletions(-) -- 2.6.1
