The following is a corresponding port of that\ncommit message.\n\nThe addition of RCU read-side critical sections within runqueue and\npriority-inheritance critical sections introduced some deadlocks,\nfor example, involving interrupts from __rcu_read_unlock() where the\ninterrupt handlers call wake_up(). This situation can cause the\ninstance of __rcu_read_unlock() invoked from interrupt to do some\nof the processing that would otherwise have been carried out by the\ntask-level instance of __rcu_read_unlock(). When the interrupt-level\ninstance of __rcu_read_unlock() is called with a scheduler lock held from\ninterrupt-entry/exit situations where in_irq() returns false, deadlock can\nresult. Of course, in a UP kernel, there are not really any deadlocks,\nbut the upper-level critical section can still be be fatally confused\nby the lower-level critical section changing things out from under it.\n\nThis commit resolves these deadlocks by using negative values of the\nper-task -\u003ercu_read_lock_nesting counter to indicate that an instance of\n__rcu_read_unlock() is in flight, which in turn prevents instances from\ninterrupt handlers from doing any special processing. Note that nested\nrcu_read_lock()/rcu_read_unlock() pairs are still permitted, but they will\nnever see -\u003ercu_read_lock_nesting go to zero, and will therefore never\ninvoke rcu_read_unlock_special(), thus preventing them from seeing the\nRCU_READ_UNLOCK_BLOCKED bit should it be set in -\u003ercu_read_unlock_special.\nThis patch also adds a check for -\u003ercu_read_unlock_special being negative\nin rcu_check_callbacks(), thus preventing the RCU_READ_UNLOCK_NEED_QS\nbit from being set should a scheduling-clock interrupt occur while\n__rcu_read_unlock() is exiting from an outermost RCU read-side critical\nsection.\n\nOf course, __rcu_read_unlock() can be preempted during the time that\n-\u003ercu_read_lock_nesting is negative. This could result in the setting\nof the RCU_READ_UNLOCK_BLOCKED bit after __rcu_read_unlock() checks it,\nand would also result it this task being queued on the corresponding\nrcu_node structure\u0027s blkd_tasks list. Therefore, some later RCU read-side\ncritical section would enter rcu_read_unlock_special() to clean up --\nwhich could result in deadlock (OK, OK, fatal confusion) if that RCU\nread-side critical section happened to be in the scheduler where the\nrunqueue or priority-inheritance locks were held.\n\nTo prevent the possibility of fatal confusion that might result from\npreemption during the time that -\u003ercu_read_lock_nesting is negative,\nthis commit also makes rcu_preempt_note_context_switch() check for\nnegative -\u003ercu_read_lock_nesting, thus refraining from queuing the task\n(and from setting RCU_READ_UNLOCK_BLOCKED) if we are already exiting\nfrom the outermost RCU read-side critical section (in other words,\nwe really are no longer actually in that RCU read-side critical\nsection). In addition, rcu_preempt_note_context_switch() invokes\nrcu_read_unlock_special() to carry out the cleanup in this case, which\nclears out the -\u003ercu_read_unlock_special bits and dequeues the task\n(if necessary), in turn avoiding needless delay of the current RCU grace\nperiod and needless RCU priority boosting.\n\nIt is still illegal to call rcu_read_unlock() while holding a scheduler\nlock if the prior RCU read-side critical section has ever had both\npreemption and irqs enabled. However, the common use case is legal,\nnamely where then entire RCU read-side critical section executes with\nirqs disabled, for example, when the scheduler lock is held across the\nentire lifetime of the RCU read-side critical section.\n\nSigned-off-by: Paul E.

This would be a very bad thing, and is supposed to\nbe prevented by the fact that the CPU_DYING CPU gets rid of all\nits callbacks before reporting the quiescent state. However,\nthere is other CPU-offline code in the kernel, and it is quite\npossible that someone will invoke RCU core processing from that\ncode. Therefore, this commit adds a warning for this case.\n\nSigned-off-by: Paul E. McKenney \u003cpaul.mckenney@linaro.org\u003e\nSigned-off-by: Paul E.

CR0 accesses\n are quite slow and expensive, don\u0027t flip the bit back and forth for\n no good reason.\n\n - Make sure that the same model works for both x86-32 and x86-64, so\n that there are no gratuitous differences between the two due to the\n way they save and restore segment state differently due to\n architectural differences that really don\u0027t matter to the FPU state.\n\n - Avoid exposing the \"preload\" state to the context switch routines,\n and in particular allow the concept of lazy state restore: if nothing\n else has used the FPU in the meantime, and the process is still on\n the same CPU, we can avoid restoring state from memory entirely, just\n re-expose the state that is still in the FPU unit.\n\n That optimized lazy restore isn\u0027t actually implemented here, but the\n infrastructure is set up for it. Of course, older CPU\u0027s that use\n \u0027fnsave\u0027 to save the state cannot take advantage of this, since the\n state saving also trashes the state.\n\nIn other words, there is now an actual _design_ to the FPU state saving,\nrather than just random historical baggage.

Which can cause problems with preemption, since a task\n switch could happen in between, and change the TS_USEDFPU bit. The\n change to TS_USEDFPU would be overwritten by the final store.\n\n In practice, this seldom happened, though, because the \u0027status\u0027 field\n was seldom used more than once, so gcc would generally tend to\n generate code that used a read-modify-write instruction and thus\n happened to avoid this problem - RMW instructions are naturally low\n fat and preemption-safe.\n\n - On x86-32, the current_thread_info() pointer would, during interrupts\n and softirqs, point to a *copy* of the real thread_info, because\n x86-32 uses %esp to calculate the thread_info address, and thus the\n separate irq (and softirq) stacks would cause these kinds of odd\n thread_info copy aliases.\n\n This is normally not a problem, since interrupts aren\u0027t supposed to\n look at thread information anyway (what thread is running at\n interrupt time really isn\u0027t very well-defined), but it confused the\n heck out of irq_fpu_usable() and the code that tried to squirrel\n away the FPU state.\n\n (It also caused untold confusion for us poor kernel developers).\n\nIt also turns out that using \u0027task_struct\u0027 is actually much more natural\nfor most of the call sites that care about the FPU state, since they\ntend to work with the task struct for other reasons anyway (ie\nscheduling).

In order to not leak FIP state from one process to another, we\nneed to do a floating point load after the fxsave of the old process,\nand before the fxrstor of the new FPU state. That resets the state to\nthe (uninteresting) kernel load, rather than some potentially sensitive\nuser information.\n\nWe used to do this directly after the FPU state save, but that is\nactually very inconvenient, since it\n\n (a) corrupts what is potentially perfectly good FPU state that we might\n want to lazy avoid restoring later and\n\n (b) on x86-64 it resulted in a very annoying ordering constraint, where\n \"__unlazy_fpu()\" in the task switch needs to be delayed until after\n the DS segment has been reloaded just to get the new DS value.\n\nCoupling it to the fxrstor instead of the fxsave automatically avoids\nboth of these issues, and also ensures that we only do it when actually\nnecessary (the FP state after a save may never actually get used). It\u0027s\nsimply a much more natural place for the leaked state cleanup.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b3b0870ef3ffed72b92415423da864f440f57ad6", "tree": "b3e128019581669d44e6634d3b1bfb169c73598d", "parents": [ "6d59d7a9f5b723a7ac1925c136e93ec83c0c3043" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 16 15:45:23 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 16 15:45:23 2012 -0800" }, "message": "i387: do not preload FPU state at task switch time\n\nYes, taking the trap to re-load the FPU/MMX state is expensive, but so\nis spending several days looking for a bug in the state save/restore\ncode.

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.

Usually the kernel first returns to the sh_mmcif\nprobe function, lets it finish and only then schedules the rescan work.\nBut sometimes, expecially under heavy system load, the work will be\nscheduled immediately before returning to the probe method. In this case\nit is important for the driver to be fully prepared for IO. For sh_mmcif\nthis means, that also the timeout work has to be initialised before\ncalling mmc_add_host(). It is also better to prepare interrupts\nbeforehand. Besides, since mmc_add_host() does card-detection itself,\nthere is no need to do it again immediately afterwards.\n\nSigned-off-by: Guennadi Liakhovetski \u003cg.liakhovetski@gmx.de\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n" }, { "commit": "e3de2be7368d2983bd7f7ddb6e9cf5ea32363128", "tree": "810c6a3d5fe404ebbe98f98561b1b9b49ac6e4fb", "parents": [ "dd13b4ed4650bb3a7d6c86b549ab66a6aa0c00d8" ], "author": { "name": "Guennadi Liakhovetski", "email": "g.liakhovetski@gmx.de", "time": "Fri Jan 06 13:06:51 2012 +0100" }, "committer": { "name": "Chris Ball", "email": "cjb@laptop.org", "time": "Mon Feb 13 20:39:03 2012 -0500" }, "message": "mmc: tmio_mmc: fix card eject during IO with DMA\n\nWhen DMA is in use and the card is ejected during IO, DMA transfers have to\nbe terminated, otherwise the dmaengine driver fails to operate properly,\nwhen the card is re-inserted.\n\nSigned-off-by: Guennadi Liakhovetski \u003cg.liakhovetski@gmx.de\u003e\nSigned-off-by: Chris Ball \u003ccjb@laptop.org\u003e\n" }, { "commit": "dd13b4ed4650bb3a7d6c86b549ab66a6aa0c00d8", "tree": "e9f3de8df407802bf1a6cd58ef6d461d100b6320", "parents": [ "3e73c36b4dc224529d0b0c0d5d69c0dacd793c42" ], "author": { "name": "Jurgen Heeks", "email": "jurgen.heeks@nokia.com", "time": "Wed Feb 01 13:30:55 2012 +0100" }, "committer": { "name": "Chris Ball", "email": "cjb@laptop.org", "time": "Mon Feb 13 20:39:02 2012 -0500" }, "message": "mmc: core: Fix comparison issue in mmc_compare_ext_csds\n\nFound this issue during code review.
