That entry-in-the-past won\u0027t\n   get removed until and interrupt happens and an interrupt won\u0027t happen\n   because the RTC only triggers an interrupt when the alarm is \"now\".\n\n   So you\u0027ll find that e.g.  \"hwclock\" will always tell you that\n   \u0027select\u0027 timed out.\n\n   So we force the interrupt work to happen at the start just in case.\"\n\nand has a patch that convert it to do things in-process rather than with\nthe worker thread, but right now it\u0027s too late to play around with this,\nso we just revert the patch that caused problems for now.\n\nReported-by: Sander Eikelenboom \u003clinux@eikelenboom.it\u003e\nRequested-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nRequested-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "RTC: Initialize kernel state from RTC\n\nMark Brown pointed out a corner case: that RTC alarms should\nbe allowed to be persistent across reboots if the hardware\nsupported it.\n\nThe rework of the generic layer to virtualize the RTC alarm\nvirtualized much of the alarm handling, and removed the\ncode used to read the alarm time from the hardware.\n\nMark noted if we want the alarm to be persistent across\nreboots, we need to re-read the alarm value into the\nvirtualized generic layer at boot up, so that the generic\nlayer properly exposes that value.\n\nThis patch restores much of the earlier removed\nrtc_read_alarm code and wires it in so that we\nset the kernel\u0027s alarm value to what we find in the\nhardware at boot time.\n\nNOTE: Not all hardware supports persistent RTC alarm state across\nsystem reset. rtc-cmos for example will keep the alarm time, but\ndisables the AIE mode irq. Applications should not expect the RTC\nalarm to be valid after a system reset. We will preserve what\nwe can, to represent the hardware state at boot, but its not\nguarenteed.\n\nFurther, in the future, with multiplexed RTC alarms, the\nsoonest alarm to fire may not be the one set via the /dev/rt\nioctls. So an application may set the alarm with RTC_ALM_SET,\nbut after a reset find that RTC_ALM_READ returns an earlier\ntime. Again, we preserve what we can, but applications should\nnot expect the RTC alarm state to persist across a system reset.\n\nBig thanks to Mark for pointing out the issue!\nThanks also to Marcelo for helping think through the solution.\n\nCC: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCC: Marcelo Roberto Jimenez \u003cmroberto@cpti.cetuc.puc-rio.br\u003e\nCC: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nCC: rtc-linux@googlegroups.com\nReported-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n"

      "message": "RTC: Rework RTC code to use timerqueue for events\n\nThis patch reworks a large portion of the generic RTC code\nto in-effect virtualize the rtc interrupt code.\n\nThe current RTC interface is very much a raw hardware interface.\nVia the proc, /dev/, or sysfs interfaces, applciations can set\nthe hardware to trigger interrupts in one of three modes:\n\nAIE: Alarm interrupt\nUIE: Update interrupt (ie: once per second)\nPIE: Periodic interrupt (sub-second irqs)\n\nThe problem with this interface is that it limits the RTC hardware\nso it can only be used by one application at a time.\n\nThe purpose of this patch is to extend the RTC code so that we can\nmultiplex multiple applications event needs onto a single RTC device.\nThis is done by utilizing the timerqueue infrastructure to manage\na list of events, which cause the RTC hardware to be programmed\nto fire an interrupt for the next event in the list.\n\nIn order to preserve the functionality of the exsting proc,/dev/ and\nsysfs interfaces, we emulate the different interrupt modes as follows:\n\nAIE: We create a rtc_timer dedicated to AIE mode interrupts. There is\nonly one per device, so we don\u0027t change existing interface semantics.\n\nUIE: Again, a dedicated rtc_timer, set for periodic mode, is used\nto emulate UIE interrupts. Again, only one per device.\n\nPIE: Since PIE mode interrupts fire faster then the RTC\u0027s clock read\ngranularity, we emulate PIE mode interrupts using a hrtimer. Again,\none per device.\n\nWith this patch, the rtctest.c application in Documentation/rtc.txt\npasses fine on x86 hardware. However, there may very well still be\nbugs, so greatly I\u0027d appreciate any feedback or testing!\n\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\nLKML Reference: \u003c1290136329-18291-4-git-send-email-john.stultz@linaro.org\u003e\nAcked-by: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nReviewed-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nCC: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Richard Cochran \u003crichardcochran@gmail.com\u003e\n"

(Several in-tree drivers have that\nissue, and I also noticed it with code reviews on several new RTC drivers.)\n\nThis patch ensures that RTC drivers never see such invalid alarm fields, by\nmoving some logic out of rtc-omap into the RTC_ALM_SET code and adding an\nexplicit check (which will prevent the issue on other code paths).\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: Scott Wood \u003cscottwood@freescale.com\u003e\nCc: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
