Otherwise, kernel maybe\npanicked.\n\nOfflining a memory block and removing a memory device can be two\ndifferent operations. Users can just offline some memory blocks without\nremoving the memory device. For this purpose, the kernel has held\nlock_memory_hotplug() in __offline_pages(). To reuse the code for\nmemory hot-remove, we repeat step 1-3 to offline all the memory blocks,\nrepeatedly lock and unlock memory hotplug, but not hold the memory\nhotplug lock in the whole operation.\n\nSigned-off-by: Wen Congyang \u003cwency@cn.fujitsu.com\u003e\nSigned-off-by: Yasuaki Ishimatsu \u003cisimatu.yasuaki@jp.fujitsu.com\u003e\nSigned-off-by: Tang Chen \u003ctangchen@cn.fujitsu.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Jiang Liu \u003cjiang.liu@huawei.com\u003e\nCc: Jianguo Wu \u003cwujianguo@huawei.com\u003e\nCc: Kamezawa Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nCc: Wu Jianguo \u003cwujianguo@huawei.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: \"H.

This causes two problems.\n- If a console driver gets deferred, then it may not be ready when\n userspace starts. For example, if a uart depends on pinctrl, then the\n uart will get deferred and /dev/console will not be available\n- __init sections will be discarded before built-in drivers are probed.\n Strictly speaking, __init functions should not be called in a drivers\n __probe path, but there are a lot of drivers (console stuff again)\n that do anyway. In the past it was perfectly safe to do so because all\n built-in drivers got probed before the end of initcalls.\n\nThis patch fixes the problem by forcing the first pass of the deferred\nlist to complete at late_initcall time. This is late enough to catch the\ndrivers that are known to have the above issues.\n\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nTested-by: Haojian Zhuang \u003chaojian.zhuang@linaro.org\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Russell King \u003clinux@arm.linux.org.uk\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: stable \u003cstable@vger.kernel.org\u003e # 3.4+\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "4419fbd4b408c3a8634b3a8dd952055d0f0b601f", "tree": "dfa48db949d2b092a92a5adb3c070db6287a37be", "parents": [ "95ecb407699825278f4031f153dbbe0f0713ff28", "191e5edf96dc4939f5db0605cc65de9f4d88d155" ], "author": { "name": "Rafael J.

PM_SUSPEND_FREEZE uses system suspend code path, thus we can get\n more power saving from the devices that does not have good RTPM support.\n\nThis state is useful for\n1) platforms that do not have STR, or have a broken STR.\n2) platforms that have an extremely low power idle state,\n which can be used to replace STR.\n\nThe following describes how PM_SUSPEND_FREEZE state works.\n1. echo freeze \u003e /sys/power/state\n2. the processes are frozen.\n3. all the devices are suspended.\n4. all the processors are blocked by a wait queue\n5. all the processors idles and enters (Deep) c-state.\n6. an interrupt fires.\n7. a processor is woken up and handles the irq.\n8. if it is a general event,\n a) the irq handler runs and quites.\n b) goto step 4.\n9. if it is a real wake event, say, power button pressing, keyboard touch, mouse moving,\n a) the irq handler runs and activate the wakeup source\n b) wakeup_source_activate() notifies the wait queue.\n c) system starts resuming from PM_SUSPEND_FREEZE\n10. all the devices are resumed.\n11. all the processes are unfrozen.\n12. system is back to working.\n\nKnown Issue:\nThe wakeup of this new PM_SUSPEND_FREEZE state may behave differently\nfrom the previous suspend state.\nTake ACPI platform for example, there are some GPEs that only enabled\nwhen the system is in sleep state, to wake the system backk from S3/S4.\nBut we are not touching these GPEs during transition to PM_SUSPEND_FREEZE.\nThis means we may lose some wake event.\nBut on the other hand, as we do not disable all the Interrupts during\nPM_SUSPEND_FREEZE, we may get some extra \"wakeup\" Interrupts, that are\nnot available for S3/S4.\n\nThe patches has been tested on an old Sony laptop, and here are the results:\n\nAverage Power:\n1. RPTM/idle for half an hour:\n 14.8W, 12.6W, 14.1W, 12.5W, 14.4W, 13.2W, 12.9W\n2. Freeze for half an hour:\n 11W, 10.4W, 9.4W, 11.3W 10.5W\n3. RTPM/idle for three hours:\n 11.6W\n4. Freeze for three hours:\n 10W\n5. Suspend to Memory:\n 0.5~0.9W\n\nAverage Resume Latency:\n1. RTPM/idle with a black screen: (From pressing keyboard to screen back)\n Less than 0.2s\n2. Freeze: (From pressing power button to screen back)\n 2.50s\n3. Suspend to Memory: (From pressing power button to screen back)\n 4.33s\n\n\u003eFrom the results, we can see that all the platforms should benefit from\nthis patch, even if it does not have Low Power S0.\n\nSigned-off-by: Zhang Rui \u003crui.zhang@intel.com\u003e\nSigned-off-by: Rafael J.

This will\naccount for the lion\u0027s share of embedded silicon devcies.\n\nA modification of the semantics for pinctrl_get() is also done:\npreviously if the pinctrl handle for a certain device was already\ntaken, the pinctrl core would return an error. Now, since the\ncore may have already default-grabbed the handle and set its\nstate to \"default\", if the handle was already taken, this will\nbe disregarded and the located, previously instanitated handle\nwill be returned to the caller.\n\nThis way all code in drivers explicitly requesting their pinctrl\nhandlers will still be functional, and drivers that want to\nexplicitly retrieve and switch their handles can still do that.\nBut if the desired functionality is just boilerplate of this\ntype in the probe() function:\n\nstruct pinctrl *p;\n\np \u003d devm_pinctrl_get_select_default(\u0026dev);\nif (IS_ERR(p)) {\n if (PTR_ERR(p) \u003d\u003d -EPROBE_DEFER)\n return -EPROBE_DEFER;\n dev_warn(\u0026dev, \"no pinctrl handle\\n\");\n}\n\nThe discussion began with the addition of such boilerplate\nto the omap4 keypad driver:\nhttp://marc.info/?l\u003dlinux-input\u0026m\u003d135091157719300\u0026w\u003d2\n\nA previous approach using notifiers was discussed:\nhttp://marc.info/?l\u003dlinux-kernel\u0026m\u003d135263661110528\u0026w\u003d2\nThis failed because it could not handle deferred probes.\n\nThis patch alone does not solve the entire dilemma faced:\nwhether code should be distributed into the drivers or\nif it should be centralized to e.g. a PM domain. But it\nsolves the immediate issue of the addition of boilerplate\nto a lot of drivers that just want to grab the default\nstate. As mentioned, they can later explicitly retrieve\nthe handle and set different states, and this could as\nwell be done by e.g. PM domains as it is only related\nto a certain struct device * pointer.\n\nChangeLog v4-\u003ev5 (Stephen):\n- Simplified the devicecore grab code.\n- Deleted a piece of documentation recommending that pins\n be mapped to a device rather than hogged.\nChangeLog v3-\u003ev4 (Linus):\n- Drop overzealous NULL checks.\n- Move kref initialization to pinctrl_create().\n- Seeking Tested-by from Stephen Warren so we do not disturb\n the Tegra platform.\n- Seeking ACK on this from Greg (and others who like it) so I\n can merge it through the pinctrl subsystem.\nChangeLog v2-\u003ev3 (Linus):\n- Abstain from using IS_ERR_OR_NULL() in the driver core,\n Russell recently sent a patch to remove it.

This may lead to problems when there are\ntwo devices such that the .suspend() callback executed for one of\nthem depends on runtime PM working for the other. In that case,\nif runtime PM has already been disabled for the second device,\nthe first one\u0027s .suspend() won\u0027t work correctly (and analogously\nfor resume).\n\nTo make those issues go away, make the PM core disable runtime PM\nfor devices right before executing subsystem/driver .suspend_late()\ncallbacks for them and enable runtime PM for them right after\nexecuting subsystem/driver .resume_early() callbacks for them. This\nway the potential conflitcs between .suspend_late()/.resume_early()\nand their runtime PM counterparts are still prevented from happening,\nbut the subtle ordering issues related to disabling/enabling runtime\nPM for devices during system suspend/resume are much easier to avoid.\n\nReported-and-tested-by: Jan-Matthias Braun \u003cjan_braun@gmx.net\u003e\nSigned-off-by: Rafael J.
