Adding 0 is without effect and the signal delivery stops.\n\nClamp the division result to minimum 1 to avoid this.\n\nProblem was reported by Seongbae Park \u003cspark@google.com\u003e, who provided\nalso an inital patch.\n\nRoland sayeth:\n\n I have had some more time to think about the problem, and to reproduce it\n using Toyo\u0027s test case. For the record, if my understanding of the problem\n is correct, this happens only in one very particular case. First, the\n expiry time has to be so soon that in cputime_t units (usually 1s/HZ ticks)\n it\u0027s \u003c nthreads so the division yields zero. Second, it only affects each\n thread that is so new that its CPU time accumulation is zero so now+0 is\n still zero and -\u003eit_*_expires winds up staying zero. For the VIRT and PROF\n clocks when cputime_t is tick granularity (or the SCHED clock on\n configurations where sched_clock\u0027s value only advances on clock ticks), this\n is not hard to arrange with new threads starting up and blocking before they\n accumulate a whole tick of CPU time. That\u0027s what happens in Toyo\u0027s test\n case.\n\n Note that in general it is fine for that division to round down to zero,\n and set each thread\u0027s expiry time to its \"now\" time. The problem only\n arises with thread\u0027s whose \"now\" value is still zero, so that now+0 winds up\n 0 and is interpreted as \"not set\" instead of \"\u003e\u003d now\". So it would be a\n sufficient and more precise fix to just use max(ticks, 1) inside the loop\n when setting each it_*_expires value.\n\n But, it does no harm to round the division up to one and always advance\n every thread\u0027s expiry time. If the thread didn\u0027t already fire timers for\n the expiry time of \"now\", there is no expectation that it will do so before\n the next tick anyway. So I followed Thomas\u0027s patch in lifting the max out\n of the loops.\n\n This patch also covers the reload cases, which are harder to write a test\n for (and I didn\u0027t try). I\u0027ve tested it with Toyo\u0027s case and it fixes that.\n\n[toyoa@mvista.com: fix: min_t -\u003e max_t]\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Daniel Walker \u003cdwalker@mvista.com\u003e\nCc: Toyo Abe \u003ctoyoa@mvista.com\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Seongbae Park \u003cspark@google.com\u003e\nCc: Peter Mattis \u003cpmattis@google.com\u003e\nCc: Rohit Seth \u003crohitseth@google.com\u003e\nCc: Martin Bligh \u003cmbligh@google.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3f4a0b917ce72ef47e438d354c433eb645218e87", "tree": "82695f890785cfe1bd14303ce04453a16bd99c01", "parents": [ "b9f5d8040b470e4f74e3266ece2969ef06d0f8aa" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Tue Oct 17 00:09:32 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Oct 17 08:18:42 2006 -0700" }, "message": "[PATCH] i386 Time: Avoid PIT SMP lockups\n\nAvoid possible PIT livelock issues seen on SMP systems (and reported by\nAndi), by not allowing it as a clocksource on SMP boxes.\n\nHowever, since the PIT may no longer be present, we have to properly handle\nthe cases where SMP systems have TSC skew and fall back from the TSC.\nSince the PIT isn\u0027t there, it would \"fall back\" to the TSC again.

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "da482792a6d1a3fbaaa25fae867b343fb4db3246", "tree": "138c187e669bbaf997780a999299fbc977568e1c", "parents": [ "57a58a9435aef3e0342ba4b2c97e0ddfea6f2c7f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Oct 05 13:06:34 2006 +0100" }, "committer": { "name": "David Howells", "email": "dhowells@warthog.cambridge.redhat.com", "time": "Thu Oct 05 13:28:27 2006 +0100" }, "message": "IRQ: Typedef the IRQ handler function type\n\nTypedef the IRQ handler function type.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1356d1e5fd256997e3d3dce0777ab787d0515c7a commit)\n" }, { "commit": "57a58a9435aef3e0342ba4b2c97e0ddfea6f2c7f", "tree": "35603f6385edf3dcd20e80a2fcf4c66c7cdc34a7", "parents": [ "d223a60106891bfe46febfacf46b20cd8509aaad" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Oct 05 13:06:34 2006 +0100" }, "committer": { "name": "David Howells", "email": "dhowells@warthog.cambridge.redhat.com", "time": "Thu Oct 05 13:28:06 2006 +0100" }, "message": "IRQ: Typedef the IRQ flow handler function type\n\nTypedef the IRQ flow handler function type.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 8e973fbdf5716b93a0a8c0365be33a31ca0fa351 commit)\n" }, { "commit": "fefd26b3b8597a11a422d950c0d4424ff33a70ad", "tree": "6794a36072635e71e5b33aec47c616bafdca65c1", "parents": [ "4a61f17378c2cdd9bd8f34ef8bd7422861d0c1f1", "038b0a6d8d32db934bba6a24e74e76e4e327a94f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:59:57 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:59:57 2006 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/davej/configh\n\n* master.kernel.org:/pub/scm/linux/kernel/git/davej/configh:\n Remove all inclusions of \u003clinux/config.h\u003e\n\nManually resolved trivial path conflicts due to removed files in\nthe sound/oss/ subdirectory.\n" }, { "commit": "18e6756a6b463e09fd3873592ec6b0579c78103d", "tree": "71e1394146450f9124041ae7f9a7f804e6c75c30", "parents": [ "a0a00cbf8ae5cea3d72e28982c06f3270420c657", "c8e649ba908954447e9a095677f6a6c8e50a37b2" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 08:15:55 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 08:15:55 2006 -0700" }, "message": "Merge branch \u0027audit.b32\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/audit-current\n\n* \u0027audit.b32\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/viro/audit-current:\n [PATCH] message types updated\n [PATCH] name_count array overrun\n [PATCH] PPID filtering fix\n [PATCH] arch filter lists with \u003c or \u003e should not be accepted\n" }, { "commit": "20e9751bd9dd6b832fd84ada27840360f7e877f1", "tree": "c598ff9cb9e540da7f8595f2c130f3674065e018", "parents": [ "4b6c2cca6eef9cc4a15350bf1c61839e12e08b84" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Oct 04 02:17:17 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 07:55:31 2006 -0700" }, "message": "[PATCH] rcu: simplify/improve batch tuning\n\nKill a hard-to-calculate \u0027rsinterval\u0027 boot parameter and per-cpu\nrcu_data.last_rs_qlen.

The two big issues I address are an artificially\nsmall cap on the number of irqs, and that MSI assumes vector \u003d\u003d irq. My\nprimary focus is on x86_64 but I have touched other architectures where\nnecessary to keep them from breaking.\n\n- To increase the number of irqs I modify the code to look at the (cpu,\n vector) pair instead of just looking at the vector.\n\n With a large number of irqs available systems with a large irq count no\n longer need to compress their irq numbers to fit. Removing a lot of brittle\n special cases.\n\n For acpi guys the result is that irq \u003d\u003d gsi.\n\n- Addressing the fact that MSI assumes irq \u003d\u003d vector takes a few more\n patches. But suffice it to say when I am done none of the generic irq code\n even knows what a vector is.\n\nIn quick testing on a large Unisys x86_64 machine we stumbled over at least\none driver that assumed that NR_IRQS could always fit into an 8 bit number.\nThis driver is clearly buggy today. But this has become a class of bugs that\nit is now much easier to hit.\n\nThis patch:\n\nThis is a minor space optimization. In practice I don\u0027t think this has any\naffect because of our alignment constraints and the other fields but there is\nnot point in chewing up an uncessary word and since we already read the flag\nfield this should improve the cache hit ratio of the irq handler.\n\nSigned-off-by: Eric W.
