This worked in the past, because registers without a\nexplicit default were assumed to have a default value of 0. This was changed in\ncommit b03622a8 (\"regmap: Ensure rbtree syncs registers set to zero properly\").\nAs a result registers, which have a raw default value of 0 are now assumed to\nhave no default. This again can result in unnecessary writes when syncing the\ncache. It will also result in unnecessary reads for e.g. the first update\noperation. In the case where readback is not possible this will even let the\nupdate operation fail, if the register has not been written to before.\n\nSo this patch removes the check. Instead it adds a check to ignore raw defaults\nfor registers which are volatile, since those registers are not cached.\n\nSigned-off-by: Lars-Peter Clausen \u003clars@metafoo.de\u003e\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: stable@vger.kernel.org\n" }, { "commit": "29bb5d4fd3140a7d5d02d858118c74a45f15c296", "tree": "bed72baeafecb0e33e816709c432595804dc711d", "parents": [ "15f51136719699d7204eeeccd66849a4d90ae426" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Wed Feb 08 15:11:17 2012 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Wed Feb 08 15:11:17 2012 -0800" }, "message": "driver-core: cpu: fix kobject warning when hotplugging a cpu\n\nDue to the sysdev conversion to struct device, the cpu objects get\nreused when adding a cpu after offlining it, which causes a big warning\nthat the kobject portion is not properly initialized.\n\nSo clear out the object before we register it again, so all is quiet.\n\nReported-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nTested-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "321bf4ed5ff5f7c62ef59f33b7eec5b154391f0a", "tree": "1fe34d7f78a690ba780d4e2ed01e48d705d345dd", "parents": [ "2885e25c422fb68208f677f944a45fce8eda2a3c" ], "author": { "name": "Yinghai Lu", "email": "yinghai@kernel.org", "time": "Mon Jan 30 13:57:12 2012 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 02 15:50:05 2012 -0800" }, "message": "drivers/base/memory.c: fix memory_dev_init() long delay\n\nOne system with 2048g ram, reported soft lockup on recent kernel.\n\n[ 34.426749] cpu_dev_init done\n[ 61.166399] BUG: soft lockup - CPU#0 stuck for 22s!

"message": "dma-buf: Introduce dma buffer sharing mechanism\n\nThis is the first step in defining a dma buffer sharing mechanism.\n\nA new buffer object dma_buf is added, with operations and API to allow easy\nsharing of this buffer object across devices.\n\nThe framework allows:\n- creation of a buffer object, its association with a file pointer, and\n associated allocator-defined operations on that buffer. This operation is\n called the \u0027export\u0027 operation.\n- different devices to \u0027attach\u0027 themselves to this exported buffer object, to\n facilitate backing storage negotiation, using dma_buf_attach() API.\n- the exported buffer object to be shared with the other entity by asking for\n its \u0027file-descriptor (fd)\u0027, and sharing the fd across.\n- a received fd to get the buffer object back, where it can be accessed using\n the associated exporter-defined operations.\n- the exporter and user to share the scatterlist associated with this buffer\n object using map_dma_buf and unmap_dma_buf operations.\n\nAtleast one \u0027attach()\u0027 call is required to be made prior to calling the\nmap_dma_buf() operation.\n\nCouple of building blocks in map_dma_buf() are added to ease introduction\nof sync\u0027ing across exporter and users, and late allocation by the exporter.\n\nFor this first version, this framework will work with certain conditions:\n- *ONLY* exporter will be allowed to mmap to userspace (outside of this\n framework - mmap is not a buffer object operation),\n- currently, *ONLY* users that do not need CPU access to the buffer are\n allowed.\n\nMore details are there in the documentation patch.\n\nThis is based on design suggestions from many people at the mini-summits[1],\nmost notably from Arnd Bergmann \u003carnd@arndb.de\u003e, Rob Clark \u003crob@ti.com\u003e and\nDaniel Vetter \u003cdaniel@ffwll.ch\u003e.\n\nThe implementation is inspired from proof-of-concept patch-set from\nTomasz Stanislawski \u003ct.stanislaws@samsung.com\u003e, who demonstrated buffer sharing\nbetween two v4l2 devices.

They are\nonly needed by their children when there\u0027s some data to transfer,\nso they may be suspended for the majority of time and resumed\non demand, when the children have data to send or receive. For this\npurpose, however, their power.ignore_children flags have to be set,\nor the PM core wouldn\u0027t allow them to be suspended while their\nchildren were active.\n\nUnfortunately, in some situations it may take too much time to\nresume such devices so that they can assist their children in\ntransferring data. For example, if such a device belongs to a PM\ndomain which goes to the \"power off\" state when that device is\nsuspended, it may take too much time to restore power to the\ndomain in response to the request from one of the device\u0027s\nchildren. In that case, if the parent\u0027s resume time is critical,\nthe domain should stay in the \"power on\" state, although it still may\nbe desirable to power manage the parent itself (e.g. by manipulating\nits clock).\n\nIn general, device PM QoS may be used to address this problem.\nNamely, if the device\u0027s children added PM QoS latency constraints\nfor it, they would be able to prevent it from being put into an\noverly deep low-power state. However, in some cases the devices\nneeding to be serviced are not the immediate children of a\n\"children-ignoring\" device, but its grandchildren or even less\ndirect descendants. In those cases, the entity wanting to add a\nPM QoS request for a given device\u0027s ancestor that ignores its\nchildren will have to find it in the first place, so introduce a new\nhelper function that may be used to achieve that. This function,\ndev_pm_qos_add_ancestor_request(), will search for the first\nancestor of the given device whose power.ignore_children flag is\nset and will add a device PM QoS latency request for that ancestor\non behalf of the caller. The request added this way may be removed\nwith the help of dev_pm_qos_remove_request() in the future, like\nany other device PM QoS latency request.\n\nSigned-off-by: Rafael J.

Unfortunately, that introduced a PM regression on SH7372\nwhose power consumption in the system \"memory sleep\" state increased\nas a result of it, because it prevented the power domain containing\nthe I2C controller from being turned off when some children of that\ncontroller were enabled to wake up the system, although the\ncontroller was not necessary for them to signal wakeup.\n\nTo fix this issue use the observation that devices whose\npower.ignore_children flag is set for runtime PM should be treated\nanalogously during system suspend. Namely, they shouldn\u0027t be\nincluded in wakeup paths going through their children. Since the\nSH7372 I2C controller\u0027s power.ignore_children flag is set, doing so\nwill restore the previous behavior of that SOC.\n\nSigned-off-by: Rafael J.
