      "message": "regulator: Provide a selector based set_voltage_sel() operation\n\nMany regulator drivers implement voltage setting by looping through a\ntable of possible values, normally because the set of available voltages\ncan\u0027t be mapped onto selectors with simple calcuation. Factor out these\nloops by providing a variant of set_voltage() which takes a selector rather\nthan a voltage range as an argument and implementing a loop through the\navailable selectors in the core.\n\nThis is not going to be suitable for use with all devices as when the\nregulator voltage can be mapped onto selector values with a simple\ncalculation the linear scan through the available values will be more\nexpensive than just doing the calculation, especially for regulators\nthat provide fine grained voltage control.\n\nSigned-off-by: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nSigned-off-by: Liam Girdwood \u003clrg@slimlogic.co.uk\u003e\n"

      "message": "mmc: Aggressive clock gating framework\n\nThis patch modifies the MMC core code to optionally call the set_ios()\noperation on the driver with the clock frequency set to 0 (gate) after\na grace period of at least 8 MCLK cycles, then restore it (ungate)\nbefore any new request. This gives the driver the option to shut down\nthe MCI clock to the MMC/SD card when the clock frequency is 0, i.e.\nthe core has stated that the MCI clock does not need to be generated.\n\nIt is inspired by existing clock gating code found in the OMAP and\nAtmel drivers and brings this up to the host abstraction.  Gating is\nperformed before and after any MMC request.\n\nThis patchset implements this for the MMCI/PL180 MMC/SD host controller,\nbut it should be simple to switch OMAP/Atmel over to using this instead.\n\nmmc_set_{gated,ungated}() add variable protection to the state holders\nfor the clock gating code.  This is particularly important when ordinary\n.set_ios() calls would race with the .set_ios() call resulting from a\ndelayed gate operation.\n\nSigned-off-by: Linus Walleij \u003clinus.walleij@stericsson.com\u003e\nReviewed-by: Chris Ball \u003ccjb@laptop.org\u003e\nTested-by: Chris Ball \u003ccjb@laptop.org\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n"

      "message": "fs: scale mntget/mntput\n\nThe problem that this patch aims to fix is vfsmount refcounting scalability.\nWe need to take a reference on the vfsmount for every successful path lookup,\nwhich often go to the same mount point.\n\nThe fundamental difficulty is that a \"simple\" reference count can never be made\nscalable, because any time a reference is dropped, we must check whether that\nwas the last reference. To do that requires communication with all other CPUs\nthat may have taken a reference count.\n\nWe can make refcounts more scalable in a couple of ways, involving keeping\ndistributed counters, and checking for the global-zero condition less\nfrequently.\n\n- check the global sum once every interval (this will delay zero detection\n  for some interval, so it\u0027s probably a showstopper for vfsmounts).\n\n- keep a local count and only taking the global sum when local reaches 0 (this\n  is difficult for vfsmounts, because we can\u0027t hold preempt off for the life of\n  a reference, so a counter would need to be per-thread or tied strongly to a\n  particular CPU which requires more locking).\n\n- keep a local difference of increments and decrements, which allows us to sum\n  the total difference and hence find the refcount when summing all CPUs. Then,\n  keep a single integer \"long\" refcount for slow and long lasting references,\n  and only take the global sum of local counters when the long refcount is 0.\n\nThis last scheme is what I implemented here. Attached mounts and process root\nand working directory references are \"long\" references, and everything else is\na short reference.\n\nThis allows scalable vfsmount references during path walking over mounted\nsubtrees and unattached (lazy umounted) mounts with processes still running\nin them.\n\nThis results in one fewer atomic op in the fastpath: mntget is now just a\nper-CPU inc, rather than an atomic inc; and mntput just requires a spinlock\nand non-atomic decrement in the common case. However code is otherwise bigger\nand heavier, so single threaded performance is basically a wash.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

      "message": "fs: rcu-walk for path lookup\n\nPerform common cases of path lookups without any stores or locking in the\nancestor dentry elements. This is called rcu-walk, as opposed to the current\nalgorithm which is a refcount based walk, or ref-walk.\n\nThis results in far fewer atomic operations on every path element,\nsignificantly improving path lookup performance. It also avoids cacheline\nbouncing on common dentries, significantly improving scalability.\n\nThe overall design is like this:\n* LOOKUP_RCU is set in nd-\u003eflags, which distinguishes rcu-walk from ref-walk.\n* Take the RCU lock for the entire path walk, starting with the acquiring\n  of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are\n  not required for dentry persistence.\n* synchronize_rcu is called when unregistering a filesystem, so we can\n  access d_ops and i_ops during rcu-walk.\n* Similarly take the vfsmount lock for the entire path walk. So now mnt\n  refcounts are not required for persistence. Also we are free to perform mount\n  lookups, and to assume dentry mount points and mount roots are stable up and\n  down the path.\n* Have a per-dentry seqlock to protect the dentry name, parent, and inode,\n  so we can load this tuple atomically, and also check whether any of its\n  members have changed.\n* Dentry lookups (based on parent, candidate string tuple) recheck the parent\n  sequence after the child is found in case anything changed in the parent\n  during the path walk.\n* inode is also RCU protected so we can load d_inode and use the inode for\n  limited things.\n* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.\n* i_op can be loaded.\n\nWhen we reach the destination dentry, we lock it, recheck lookup sequence,\nand increment its refcount and mountpoint refcount. RCU and vfsmount locks\nare dropped. This is termed \"dropping rcu-walk\". If the dentry refcount does\nnot match, we can not drop rcu-walk gracefully at the current point in the\nlokup, so instead return -ECHILD (for want of a better errno). This signals the\npath walking code to re-do the entire lookup with a ref-walk.\n\nAside from the final dentry, there are other situations that may be encounted\nwhere we cannot continue rcu-walk. In that case, we drop rcu-walk (ie. take\na reference on the last good dentry) and continue with a ref-walk. Again, if\nwe can drop rcu-walk gracefully, we return -ECHILD and do the whole lookup\nusing ref-walk. But it is very important that we can continue with ref-walk\nfor most cases, particularly to avoid the overhead of double lookups, and to\ngain the scalability advantages on common path elements (like cwd and root).\n\nThe cases where rcu-walk cannot continue are:\n* NULL dentry (ie. any uncached path element)\n* parent with d_inode-\u003ei_op-\u003epermission or ACLs\n* dentries with d_revalidate\n* Following links\n\nIn future patches, permission checks and d_revalidate become rcu-walk aware. It\nmay be possible eventually to make following links rcu-walk aware.\n\nUncached path elements will always require dropping to ref-walk mode, at the\nvery least because i_mutex needs to be grabbed, and objects allocated.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"
