Reported by Joakim\n Hernberg.\n\n - We had a fix in v3.12.8-rt11 for ip_send_unicast_reply() which I\n dropped in v3.18.8 based -RT due code change and I assumed the need\n for extra serialization is no longer required. As it turns out it is\n still required :)\n\n - While looking around a similar serialisation might be required in\n icmp_sk().

It isn\u0027t toxic but it shouldn\u0027t\n happen. Noticed by Thomas Gleixner.\n\n - The way the preempt counter is accessed on non-x86 architectures\n allowed the compiler to reorder the code slightly. This led to\n decrementing the preempt counter, checking for the need resched bit\n followed by writing the counter back. An interrupt between the last\n two steps will lead to a missing preemption point and thus high\n latencies. Patch by Peter Zijlstra.\n\n - The recorded preemption counter in event trace points (such as\n raw_syscall_entry) are off by one because each trace point\n increments the counter. This has been corrected.\n\n - It is now ensured that there are no attempts to print from IRQ or\n NMI context. On certain events such as hard-lockup-detector we would\n attempt to grab sleeping locks.\n\n - Allow lru_add_drain_all() to perform its work remotely.

It does now. However AT91 does not yet boot. There are\n two issues:\n - the free_irq() from irq-off region is not good and triggers a\n warning because it is invoked twice. This will be addressed later,\n the current patch is not bulletproof and not yet part of the series.\n - The PMC driver invokes request_irq() very early which leads to a\n NULL pointer exception (non-RT with threaded interrupts has the same\n problem). A longer explanation by Alexandre Belloni and his current\n patch series he refers to can be found at:\n http://lkml.kernel.org/r/1452997394-8554-1-git-send-email-alexandre.belloni@free-electrons.com\n\n- Using a virtual network device (like a bridge) could lead to a \"Dead\n loop\" message the packet dropped. This problem has been fixed.\n\n- Julia Lawall sent a patch against hwlat_detector to \"move constants to\n the right of binary operators\".\n\n- Carsten Emde sent a patch to fix the latency histogram tracer.\n\n- Mike Galbraith reported that the softirq ate about 25% CPU time doing\n nothing. The problem was fixed.\n\n- Grygorii Strashko pointed out that two RCU/ksoftirqd changes that were\n made to the non-RT version of the code did not make to the RT version.\n This was corrected.\n\n- btrfs forgot to initialize a seqcount variable which prints a warning\n if used with lockdep.\n\n- A few users napi_alloc_cache() were not protected against reentrance.\n\n- Grygorii Strashko fixed highmem on ARM.\n\n- Mike Galbraith reported that all tasks run on CPU0 even on a system\n with more than one. Problem fixed by Thomas Gleixner.\n\n- Anders Roxell sent two patches (against coupled and vsp1) because they\n did not compile and printed a warning on -RT.\n\n- Mike Galbraith pointed out that we forgot to check for\n NEED_RESCHED_LAZY in an exit path on X86 and provided a patch.\n\n- Mike Galbraith pointed out that we don\u0027t consider the preempt_lazy_count\n in the common preemption check and provided a patch. With this fixed,\n the sched_other performance should improve.\n\n- A high network load could lead to RCU stalls followed by the OOM\n killer. Say a slower ARM with on a GBIT link running RT tasks, doing\n network IO (at a RT prio) and getting shot with the flood ping at a\n high rate. NAPI does not really kick in because each time NAPI tries\n defer processing it starts again in the context of the IRQ thread of\n the network driver.\n This has been fixed in two steps:\n - once the NAPI budget is up, we schedule ksoftirqd. This works now on\n -RT, too\n - ksoftirqd runs now at SCHED_OTHER priority like the on !RT. Now the\n scheduler can preempt ksoftirqd and let RCU do its job. The timer\n and hrtimer softirq processing happens now in ktimersoftd which runs\n at SCHED_FIFO (as ksoftirqd used to).\n\n- Grygorii Strashko pointed out that if RCU_EXPERT is not enabled then\n we can\u0027t select RCU_BOOST. Therefore RCU_EXPERT is default y on RT.\n\n- Grygorii Strashko pointed out the we miss to check for\n NEED_RESCHED_LAZY in an exit path on ARM. This has been fixed on ARM\n and on ARM64 as well.\n\nThis was a lot and I hope I forgot nothing important.\n\nKnown issues:\n - bcache stays disabled\n\n - CPU hotplug is not better than before\n\n - The netlink_release() OOPS, reported by Clark, is still on the\n list, but unsolved due to lack of information\n\nThe delta patch against 4.4-rt2 is appended below and can be found here:\n\n https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.4/incr/patch-4.4-rt2-rt3.patch\n\nYou can get this release via the git tree at:\n\n git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v4.4-rt3\n\nThe RT patch against 4.1.13 can be found here:\n\n https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4-rt3.patch.xz\n\nThe split quilt queue is available at:\n\n https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.4/patches-4.4-rt3.tar.xz\n\nSebastian\n\nSigned-off-by: Sebastian Andrzej Siewior \u003cbigeasy@linutronix.de\u003e\n" }, { "commit": "c5f0ba59007d49527ec8c89cd6ff721a8f5c294e", "tree": "affd020051f4f6c0c4d52128ce6e49f9901daeeb", "parents": [ "7bbd599b8bb8ca9e9b7cf0fdf77da61fc1eb7d11" ], "author": { "name": "Sebastian Andrzej Siewior", "email": "bigeasy@linutronix.de", "time": "Tue Jan 12 16:23:00 2016 +0100" }, "committer": { "name": "Sebastian Andrzej Siewior", "email": "bigeasy@linutronix.de", "time": "Tue Jan 12 16:23:00 2016 +0100" }, "message": "[ANNOUNCE] 4.4-rt2\n\nSigned-off-by: Sebastian Andrzej Siewior \u003cbigeasy@linutronix.de\u003e\n" }, { "commit": "7bbd599b8bb8ca9e9b7cf0fdf77da61fc1eb7d11", "tree": "a218f64a3fd415012d135ec0c1202211d66600fa", "parents": [ "1ccda4237a810cc0ef5c801ed1fd512543c70785" ], "author": { "name": "Sebastian Andrzej Siewior", "email": "bigeasy@linutronix.de", "time": "Wed Dec 23 23:25:26 2015 +0100" }, "committer": { "name": "Sebastian Andrzej Siewior", "email": "bigeasy@linutronix.de", "time": "Wed Dec 23 23:52:17 2015 +0100" }, "message": "[ANNOUNCE] 4.4-rc6-rt1\n\nPlease don\u0027t continue reading before christmas eve (or morning,\ndepending on your schedule).
