This callback expect to be handled on irq work own interrupt otherwise we run into a deadlock. * Enforce nohz_full to depend on arch to support irq work interrupts. Without that support, irq work run from the tick but the tick can be shutdown on nohz full. * Nohz init code consolidation Thanks, Frederic --- Frederic Weisbecker (7): nohz: Move nohz full init call to tick init irq_work: Force raised irq work to run on irq work interrupt x86: Tell irq work about self IPI support arm: Tell irq work about self IPI support arm64: Tell irq work about self IPI support nohz: Consolidate nohz full init code nohz: nohz full depends on irq work self IPI support Peter Zijlstra (1): irq_work: Introduce arch_irq_work_has_interrupt() arch/alpha/include/asm/Kbuild | 1 + arch/arc/include/asm/Kbuild | 1 + arch/arm/include/asm/irq_work.h | 11 ++++++++ arch/arm/kernel/smp.c | 2 +- arch/arm64/include/asm/Kbuild | 2 +- arch/arm64/include/asm/irq_work.h | 11 ++++++++ arch/arm64/include/asm/smp.h | 2 ++ arch/arm64/kernel/smp.c | 2 +- arch/avr32/include/asm/Kbuild | 1 + arch/blackfin/include/asm/Kbuild | 1 + arch/c6x/include/asm/Kbuild | 1 + arch/cris/include/asm/Kbuild | 1 + arch/frv/include/asm/Kbuild | 1 + arch/hexagon/include/asm/Kbuild | 1 + arch/ia64/include/asm/Kbuild | 1 + arch/m32r/include/asm/Kbuild | 1 + arch/m68k/include/asm/Kbuild | 1 + arch/metag/include/asm/Kbuild | 1 + arch/microblaze/include/asm/Kbuild | 1 + arch/mips/include/asm/Kbuild | 1 + arch/mn10300/include/asm/Kbuild | 1 + arch/openrisc/include/asm/Kbuild | 1 + arch/parisc/include/asm/Kbuild | 1 + arch/powerpc/include/asm/Kbuild | 1 + arch/s390/include/asm/Kbuild | 1 + arch/score/include/asm/Kbuild | 1 + arch/sh/include/asm/Kbuild | 1 + arch/sparc/include/asm/Kbuild | 1 + arch/tile/include/asm/Kbuild | 1 + arch/um/include/asm/Kbuild | 1 + arch/unicore32/include/asm/Kbuild | 1 + arch/x86/include/asm/irq_work.h | 11 ++++++++ arch/x86/kernel/irq_work.c | 2 +- arch/xtensa/include/asm/Kbuild | 1 + include/asm-generic/irq_work.h | 10 ++++++++ include/linux/irq_work.h | 3 +++ include/linux/tick.h | 2 -- init/main.c | 1 - kernel/irq_work.c | 15 +++++++++-- kernel/time/tick-common.c | 1 + kernel/time/tick-internal.h | 7 +++++ kernel/time/tick-sched.c | 52 ++++++++++++++++++++++++-------------- kernel/time/timer.c | 2 +- 43 files changed, 133 insertions(+), 29 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
