while we traverse\nthe tree, even if the returned pointer will still be valid.\n\nWhile preparing a patch to expand the context in which\nirq_radix_revmap_lookup will be called, I realized that the\nradix tree was not locked.\n\nWhen asked\n\n For a normal call_rcu usage, is it allowed to read the structure in\n irq_enter / irq_exit, without additional rcu_read_lock? Could an\n element freed with call_rcu advance with the cpu still between\n irq_enter/irq_exit (and irq_disabled())?\n\nPaul McKenney replied:\n\n Absolutely illegal to do so. OK for call_rcu_sched(), but a\n flaming bug for call_rcu().\n\n And thank you very much for finding this!!!\n\nFurther analysis:\n\nIn the current CONFIG_TREE_RCU implementation. CONFIG_TREE_PREEMPT_RCU\n(and CONFIG_TINY_PREEMPT_RCU) uses explicit counters.\n\nThese counters are reflected from per-CPU to global in the\nscheduling-clock-interrupt handler, so disabling irq does prevent the\ngrace period from completing. But there are real-time implementations\n(such as the one use by the Concurrent guys) where disabling irq\ndoes -not- prevent the grace period from completing.\n\nWhile an alternative fix would be to switch radix-tree to rcu_sched, I\ndon\u0027t want to audit the other users of radix trees (nor put alternative\nfreeing in the library). The normal overhead for rcu_read_lock and\nunlock are a local counter increment and decrement.\n\nThis does not show up in the rcu lockdep because in 2.6.34 commit\n2676a58c98 (radix-tree: Disable RCU lockdep checking in radix tree)\ndeemed it too hard to pass the condition of the protecting lock\nto the library.\n\nSigned-off-by: Milton Miller \u003cmiltonm@bga.com\u003e\nReviewed-by: Paul E.

However, several interrupt\ncontrollers only provide a single software triggered interrupt that\ncan be delivered to each cpu. To resolve this limitation, each smp_ops\nimplementation created a per-cpu variable that is manipulated with atomic\nbitops. Since these lines will be contended they are optimialy marked as\nshared_aligned and take a full cache line for each cpu. Distro kernels\nmay have 2 or 3 of these in their config, each taking per-cpu space\neven though at most one will be in use.\n\nThis consolidation removes smp_message_recv and replaces the single call\nactions cases with direct calls from the common message recognition loop.\nThe complicated debugger ipi case with its muxed crash handling code is\nmoved to debug_ipi_action which is now called from the demux code (instead\nof the multi-message action calling smp_message_recv).\n\nI put a call to reschedule_action to increase the likelyhood of correctly\nmerging the anticipated scheduler_ipi() hook coming from the scheduler\ntree; that single required call can be inlined later.\n\nThe actual message decode is a copy of the old pseries xics code with its\nmemory barriers and cache line spacing, augmented with a per-cpu unsigned\nlong based on the book-e doorbell code. The optional data is set via a\ncallback from the implementation and is passed to the new cause-ipi hook\nalong with the logical cpu number. While currently only the doorbell\nimplemntation uses this data it should be almost zero cost to retrieve and\npass it -- it adds a single register load for the argument from the same\ncache line to which we just completed a store and the register is dead\non return from the call. I extended the data element from unsigned int\nto unsigned long in case some other code wanted to associate a pointer.\n\nThe doorbell check_self is replaced by a call to smp_muxed_ipi_resend,\nconditioned on the CPU_DBELL feature. The ifdef guard could be relaxed\nto CONFIG_SMP but I left it with BOOKE for now.\n\nAlso, the doorbell interrupt vector for book-e was not calling irq_enter\nand irq_exit, which throws off cpu accounting and causes code to not\nrealize it is running in interrupt context.
