0-day robot reported graph-tracing made the cpuidle-vs-rcu rework go splat. These patches appear to cure this, the ftrace selftest now runs to completion without spamming scary messages to dmesg. Since v1: - fixed recursive RCU splats - fixed psci thingies for arm (null) - improved the tracing WARN (rostedt) - fixed TRACE_PREEMPT_TOGGLE (null) --- arch/x86/include/asm/atomic64_32.h | 44 +++++++++++++++++++------------------- arch/x86/include/asm/atomic64_64.h | 36 +++++++++++++++---------------- arch/x86/include/asm/kvmclock.h | 2 +- arch/x86/include/asm/paravirt.h | 2 +- arch/x86/include/asm/pvclock.h | 3 ++- arch/x86/kernel/cpu/vmware.c | 2 +- arch/x86/kernel/kvmclock.c | 6 +++--- arch/x86/kernel/pvclock.c | 22 +++++++++++++------ arch/x86/kernel/tsc.c | 7 +++--- arch/x86/xen/time.c | 12 +++++++++-- drivers/cpuidle/cpuidle.c | 2 +- drivers/cpuidle/poll_state.c | 2 -- drivers/firmware/psci/psci.c | 31 ++++++++++++++++----------- include/linux/context_tracking.h | 27 +++++++++++++++++++++++ include/linux/math64.h | 4 ++-- include/linux/sched/clock.h | 8 +++---- include/linux/trace_recursion.h | 18 ++++++++++++++++ kernel/locking/lockdep.c | 3 +++ kernel/panic.c | 5 +++++ kernel/sched/clock.c | 27 +++++++++++++++++------ kernel/trace/trace_preemptirq.c | 6 ++---- lib/bug.c | 15 ++++++++++++- 22 files changed, 192 insertions(+), 92 deletions(-) _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
