Fix from Rafael J Wysocki removes that limit and makes memory hotplug work again. - A change made in 3.9 uncovered a bug in the ACPI processor driver preventing NUMA nodes from being put offline due to an ordering issue. Fix from Yasuaki Ishimatsu changes the ordering to make things work again. - One of the recent ACPI video commits (that hasn't been reverted so far) uncovered a bug in the code handling quirky BIOSes that caused some Asus machines to boot with backlight completely off which made it quite difficult to use them afterward. Fix from Felipe Contreras improves the quirk to cover this particular case correctly. - A cpufreq user space interface change made in 3.10 inadvertently renamed the ignore_nice_load sysfs attribute to ignore_nice which resulted in some confusion. Fix from Viresh Kumar changes the name back to ignore_nice_load. - An initialization ordering change made in 3.9 broke cpufreq on loongson2 boards. Fix from Aaro Koskinen restores the correct initialization ordering there. - Fix breakage resulting from a mistake made in 3.9 and causing the detection of some graphics adapters (that were detected correctly before) to fail. There are two objects representing the same PCIe port in the affected systems' ACPI tables and both appear as "enabled" and we are expected to guess which one to use. We used to choose the right one before by pure luck, but when we tried to address another similar corner case, the luck went away. This time we try to make our guessing a bit more educated which is reported to work on those systems. - The /proc/acpi/wakeup interface code is missing some locking which may lead to breakage if that file is written or read during hotplug of wakeup devices. That should be rare but still possible, so it's better to start using the appropriate locking there. * tag 'pm+acpi-3.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: Try harder to resolve _ADR collisions for bridges cpufreq: rename ignore_nice as ignore_nice_load cpufreq: loongson2: fix regression related to clock management ACPI / processor: move try_offline_node() after acpi_unmap_lsapic() ACPI: Drop physical_node_id_bitmap from struct acpi_device ACPI / PM: Walk physical_node_list under physical_node_lock ACPI / video: improve quirk check in acpi_video_bqc_quirk() | 09 August 2013, 22:07:19 UTC |

| 201d3df | Oleg Nesterov | 09 August 2013, 15:19:13 UTC | dlm: kill the unnecessary and wrong device_close()->recalc_sigpending() device_close()->recalc_sigpending() is not needed, sigprocmask() takes care of TIF_SIGPENDING correctly. And without ->siglock it is racy and wrong, it can wrongly clear TIF_SIGPENDING and miss a signal. But even with this patch device_close() is still buggy: 1. sigprocmask() should not be used, we have set_task_blocked(), but this is minor. 2. We should never block SIGKILL or SIGSTOP, and this is what the code tries to do. 3. This can't protect against SIGKILL or SIGSTOP anyway. Another thread can do signal_wake_up(), say, do_signal_stop() or complete_signal() or debugger. 4. sigprocmask(SIG_BLOCK, allsigs) doesn't necessarily clears TIF_SIGPENDING, say, freezing() or ->jobctl. 5. device_write() looks equally wrong by the same reason. Looks like, this tries to protect some wait_event_interruptible() logic from signals, it should be turned into uninterruptible wait. Or we need to implement something like signals_stop/start for such a use-case.

| 8e5654c | Jiri Kosina | 09 August 2013, 09:34:19 UTC | Revert "HID: hid-logitech-dj: querying_devices was never set" This reverts commit 407a2c2a4d85100c8c67953e4bac2f4a6c942335. Explanation provided by Benjamin Tissoires: Commit "HID: hid-logitech-dj, querying_devices was never set" activate a flag which guarantees that we do not ask the receiver for too many enumeration. When the flag is set, each following enumeration call is discarded (the usb request is not forwarded to the receiver). The flag is then released when the driver receive a pairing information event, which normally follows the enumeration request. However, the USB3 bug makes the driver think the enumeration request has been forwarded to the receiver. However, it is actually not the case because the USB stack returns -EPIPE. So, when a new unknown device appears, the workaround consisting in asking for a new enumeration is not working anymore: this new enumeration is discarded because of the flag, which is never reset. A solution could be to trigger a timeout before releasing it, but for now, let's just revert the patch.

| 60f75b8 | Rafael J. Wysocki | 07 August 2013, 20:55:00 UTC | ACPI: Try harder to resolve _ADR collisions for bridges In theory, under a given ACPI namespace node there should be only one child device object with _ADR whose value matches a given bus address exactly. In practice, however, there are systems in which multiple child device objects under a given parent have _ADR matching exactly the same address. In those cases we use _STA to determine which of the multiple matching devices is enabled, since some systems are known to indicate which ACPI device object to associate with the given physical (usually PCI) device this way. Unfortunately, as it turns out, there are systems in which many device objects under the same parent have _ADR matching exactly the same bus address and none of them has _STA, in which case they all should be regarded as enabled according to the spec. Still, if those device objects are supposed to represent bridges (e.g. this is the case for device objects corresponding to PCIe ports), we can try harder and skip the ones that have no child device objects in the ACPI namespace. With luck, we can avoid using device objects that we are not expected to use this way. Although this only works for bridges whose children also have ACPI namespace representation, it is sufficient to address graphics adapter detection issues on some systems, so rework the code finding a matching device ACPI handle for a given bus address to implement this idea. Introduce a new function, acpi_find_child(), taking three arguments: the ACPI handle of the device's parent, a bus address suitable for the device's bus type and a bool indicating if the device is a bridge and make it work as outlined above. Reimplement the function currently used for this purpose, acpi_get_child(), as a call to acpi_find_child() with the last argument set to 'false' and make the PCI subsystem use acpi_find_child() with the bridge information passed as the last argument to it. [Lan Tianyu notices that it is not sufficient to use pci_is_bridge() for that, because the device's subordinate pointer hasn't been set yet at this point, so use hdr_type instead.] This change fixes a regression introduced inadvertently by commit 33f767d (ACPI: Rework acpi_get_child() to be more efficient) which overlooked the fact that for acpi_walk_namespace() "post-order" means "after all children have been visited" rather than "on the way back", so for device objects without children and for namespace walks of depth 1, as in the acpi_get_child() case, the "post-order" callbacks ordering is actually the same as the ordering of "pre-order" ones. Since that commit changed the namespace walk in acpi_get_child() to terminate after finding the first matching object instead of going through all of them and returning the last one, it effectively changed the result returned by that function in some rare cases and that led to problems (the switch from a "pre-order" to a "post-order" callback was supposed to prevent that from happening, but it was ineffective). As it turns out, the systems where the change made by commit 33f767d actually matters are those where there are multiple ACPI device objects representing the same PCIe port (which effectively is a bridge). Moreover, only one of them, and the one we are expected to use, has child device objects in the ACPI namespace, so the regression can be addressed as described above.

| 1e385f6 | Yasuaki Ishimatsu | 06 August 2013, 10:11:11 UTC | ACPI / processor: move try_offline_node() after acpi_unmap_lsapic() try_offline_node() checks that all CPUs associated with the given node have been removed by using cpu_present_bits. If all cpus related to that node have been removed, try_offline_node() clears the node information. However, try_offline_node() called from acpi_processor_remove() never clears the node information. For disabling cpu_present_bits, acpi_unmap_lsapic() needs be called. Yet, acpi_unmap_lsapic() is called after try_offline_node() has run. So when try_offline_node() runs, the CPU's cpu_present_bits is always set. Fix the issue by moving try_offline_node() after acpi_unmap_lsapic().

Note that Bspec is horribly misguided on i965g/gm, so we don't have any other data points besides that it seems to make machines work better. With this changes all the bits in PORT_HOTPLUG_STAT for the digital ports are ordered the same way. This seems to agree with what register dumps from the hpd storm handling code shows, where the LIVE bit and the short/long pulse STATUS bits light up at the same time with this enumeration (but no with the one from Bspec). Also tested on my gm45 which has two DP+ ports, and everything seems to still work as expected.

It's with the return of braille_register_console(). As anything other than NULL is considered a failure. But for those of us that have CONFIG_A11Y_BRAILLE_CONSOLE set but do not define a "brl" or "brl=" on the command line, we still may want a console that those with sight can still use.

Wysocki | 06 August 2013, 12:32:54 UTC | ACPI: Drop physical_node_id_bitmap from struct acpi_device The physical_node_id_bitmap in struct acpi_device is only used for looking up the first currently unused dependent phyiscal node ID by acpi_bind_one(). It is not really necessary, however, because acpi_bind_one() walks the entire physical_node_list of the given device object for sanity checking anyway and if that list is always sorted by node_id, it is straightforward to find the first gap between the currently used node IDs and use that number as the ID of the new list node. This also removes the artificial limit of the maximum number of dependent physical devices per ACPI device object, which now depends only on the capacity of unsigend int. As a result, it fixes a regression introduced by commit e2ff394 (ACPI / memhotplug: Bind removable memory blocks to ACPI device nodes) that caused acpi_memory_enable_device() to fail when the number of 128 MB blocks within one removable memory module was greater than 32.

Since each of those functions may be run at any time as a result of a user space action, the lack of appropriate locking in them may lead to a kernel crash if that happens during device hot-add or hot-remove involving the device object in question.

I think that this is missing the point: flink is *already* allowed without privilege as long as /proc is mounted -- it's called AT_SYMLINK_FOLLOW. Now that O_TMPFILE is here, the ability to create a file with O_TMPFILE, write it, and link it in is very convenient. The only problem is that it requires that /proc be mounted so that you can do: linkat(AT_FDCWD, "/proc/self/fd/<tmpfd>", dfd, path, AT_SYMLINK_NOFOLLOW) This sucks -- it's much nicer to do: linkat(tmpfd, "", dfd, path, AT_EMPTY_PATH) Let's allow it.

Fortunately, the same change allows a much simpler race avoidance - all we need to do is remove the procfs entries in the very beginning of reiserfs ->kill_sb(); that'll guarantee that pointer to superblock will remain valid for the duration for procfs IO, so we don't need sget() to keep the sucker alive.

| b3b301c | Felipe Contreras | 03 August 2013, 21:00:25 UTC | ACPI / video: improve quirk check in acpi_video_bqc_quirk() If the _BCL package ordering is descending, the first level (br->levels[2]) is likely to be 0, and if the number of levels matches the number of steps, we might confuse a returned level to mean the index. For example: current_level = max_level = 100 test_level = 0 returned level = 100 In this case 100 means the level, not the index, and _BCM failed. Still, if the _BCL package ordering is descending, the index of level 0 is also 100, so we assume _BQC is indexed, when it's not. This causes all _BQC calls to return bogus values causing weird behavior from the user's perspective. For example: xbacklight -set 10; xbacklight -set 20; would flash to 90% and then slowly down to the desired level (20). The solution is simple; test anything other than the first level (e.g. 1).

This patch removes sti_secondary_start from _INIT section, there are 2 reason for this removal. 1. discarding such a small code does not save much, given the RAM sizes. 2. Having this code discarded, creates corruption issue when we boot smp-kernel with nrcpus=1 or with single cpu node in DT.

This series is based power tree on production board 750-2628-XXX platform. Unfortunately, the wrong voltages may be detrimental to OMAP5 as they supply hardware blocks at voltages that are out of specification.

The first fixes the a gpio controller register address. I didn't see any acks from the devicetree maintainers, so I've copied them on this pull request. The change itself is minor, and just to the register address. The second change removes the gpiomux V1 code from MSM.
