ACPI: container: Use acpi_dev_for_each_child() Instead of walking the list of children of an ACPI device directly, use acpi_dev_for_each_child() to carry out an action for all of the given ACPI device's children. This will help to eliminate the children list head from struct acpi_device as it is redundant and it is used in questionable ways in some places (in particular, locking is needed for walking the list pointed to it safely, but it is often missing).

ACPI / hotplug: Generate online uevents for ACPI containers Commit 46394fd01 (ACPI / hotplug: Move container-specific code out of the core) removed the generation of "online" uevents for containers, because "add" uevents are now generated for them automatically when container system devices are registered. However, there are user space tools that need to be notified when the container and all of its children have been enumerated, which doesn't happen any more. For this reason, add a mechanism allowing "online" uevents to be generated for ACPI containers after enumerating the container along with all of its children.

ACPI / dock: Dispatch dock notifications from the global notify handler The ACPI dock station code carries out an extra namespace scan before the main one in order to find and register all of the dock device objects. Then, it registers a notify handler for each of them for handling dock events. However, dock device objects need not be scanned for upfront. They very well can be enumerated and registered during the first phase of the main namespace scan, before attaching scan handlers and ACPI drivers to ACPI device objects. Then, the dependent devices can be added to the in the second phase. That makes it possible to drop the extra namespace scan, so do it. Moreover, it is not necessary to register notify handlers for all of the dock stations' namespace nodes, becuase notifications may be dispatched from the global notify handler for them. Do that and drop two functions used for dock notify handling, acpi_dock_deferred_cb() and dock_notify_handler(), that aren't necessary any more. Finally, some dock station objects have _HID objects matching the ACPI container scan handler which causes it to claim those objects and try to handle their hotplug, but that is not a good idea, because those objects have their own special hotplug handling anyway. For this reason, the hotplug_notify flag should not be set for ACPI device objects representing dock stations and the container scan handler should be made ignore those objects, so make that happen.

ACPI / hotplug / driver core: Handle containers in a special way ACPI container devices require special hotplug handling, at least on some systems, since generally user space needs to carry out system-specific cleanup before it makes sense to offline devices in the container. However, the current ACPI hotplug code for containers first attempts to offline devices in the container and only then it notifies user space of the container offline. Moreover, after commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace), ACPI device objects representing containers are present as long as the ACPI namespace nodes corresponding to them are present, which may be forever, even if the container devices are physically detached from the system (the return values of the corresponding _STA methods change in those cases, but generally the namespace nodes themselves are still there). Thus it is useful to introduce entities representing containers that will go away during container hot-unplug. The goal of this change is to address both the above issues. The idea is to create a "companion" container system device for each of the ACPI container device objects during the initial namespace scan or on a hotplug event making the container present. That system device will be unregistered on container removal. A new bus type for container devices is added for this purpose, because device offline and online operations need to be defined for them. The online operation is a trivial function that is always successful and the offline uses a callback pointed to by the container device's offline member. For ACPI containers that callback simply walks the list of ACPI device objects right below the container object (its children) and checks if all of their physical companion devices are offline. If that's not the case, it returns -EBUSY and the container system devivce cannot be put offline. Consequently, to put the container system device offline, it is necessary to put all of the physical devices depending on its ACPI companion object offline beforehand. Container system devices created for ACPI container objects are initially online. They are created by the container ACPI scan handler whose hotplug.demand_offline flag is set. That causes acpi_scan_hot_remove() to check if the companion container system device is offline before attempting to remove an ACPI container or any devices below it. If the check fails, a KOBJ_CHANGE uevent is emitted for the container system device in question and user space is expected to offline all devices below the container and the container itself in response to it. Then, user space can finalize the removal of the container with the help of its ACPI device object's eject attribute in sysfs.

ACPI / hotplug: Fix concurrency issues and memory leaks This changeset is aimed at fixing a few different but related problems in the ACPI hotplug infrastructure. First of all, since notify handlers may be run in parallel with acpi_bus_scan(), acpi_bus_trim() and acpi_bus_hot_remove_device() and some of them are installed for ACPI handles that have no struct acpi_device objects attached (i.e. before those objects are created), those notify handlers have to take acpi_scan_lock to prevent races from taking place (e.g. a struct acpi_device is found to be present for the given ACPI handle, but right after that it is removed by acpi_bus_trim() running in parallel to the given notify handler). Moreover, since some of them call acpi_bus_scan() and acpi_bus_trim(), this leads to the conclusion that acpi_scan_lock should be acquired by the callers of these two funtions rather by these functions themselves. For these reasons, make all notify handlers that can handle device addition and eject events take acpi_scan_lock and remove the acpi_scan_lock locking from acpi_bus_scan() and acpi_bus_trim(). Accordingly, update all of their users to make sure that they are always called under acpi_scan_lock. Furthermore, since eject operations are carried out asynchronously with respect to the notify events that trigger them, with the help of acpi_bus_hot_remove_device(), even if notify handlers take the ACPI scan lock, it still is possible that, for example, acpi_bus_trim() will run between acpi_bus_hot_remove_device() and the notify handler that scheduled its execution and that acpi_bus_trim() will remove the device node passed to acpi_bus_hot_remove_device() for ejection. In that case, the struct acpi_device object obtained by acpi_bus_hot_remove_device() will be invalid and not-so-funny things will ensue. To protect agaist that, make the users of acpi_bus_hot_remove_device() run get_device() on ACPI device node objects that are about to be passed to it and make acpi_bus_hot_remove_device() run put_device() on them and check if their ACPI handles are not NULL (make acpi_device_unregister() clear the device nodes' ACPI handles for that check to work). Finally, observe that acpi_os_hotplug_execute() actually can fail, in which case its caller ought to free memory allocated for the context object to prevent leaks from happening. It also needs to run put_device() on the device node that it ran get_device() on previously in that case. Modify the code accordingly. Signed-off-by: Rafael J.

ACPI: Make acpi_bus_scan() and acpi_bus_add() take only one argument The callers of acpi_bus_add() usually assume that if it has succeeded, then a struct acpi_device object has been attached to the handle passed as the first argument. Unfortunately, however, this assumption is wrong, because acpi_bus_scan(), and acpi_bus_add() too as a result, may return a pointer to a different struct acpi_device object on success (it may be an object corresponding to one of the descendant ACPI nodes in the namespace scope below that handle). For this reason, the callers of acpi_bus_add() who care about whether or not a struct acpi_device object has been created for its first argument need to check that using acpi_bus_get_device() anyway, so the second argument of acpi_bus_add() is not really useful for them. The same observation applies to acpi_bus_scan() executed directly from acpi_scan_init(). Therefore modify the relevant callers of acpi_bus_add() to check the existence of the struct acpi_device in question with the help of acpi_bus_get_device() and drop the no longer necessary second argument of acpi_bus_add(). Accordingly, modify acpi_scan_init() to use acpi_bus_get_device() to get acpi_root and drop the no longer needed second argument of acpi_bus_scan(). Signed-off-by: Rafael J.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

This change adds an additional parameter for a post-order callback which will be more useful for bus scans. ACPICA BZ 779. Also update the external calls to acpi_walk_namespace. http://www.acpica.org/bugzilla/show_bug.cgi?id=779 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

ACPI: Move definition of PREFIX from acpi_bus.h to internal..h Linux/ACPI core files using internal.h all PREFIX "ACPI: ", however, not all ACPI drivers use/want it -- and they should not have to #undef PREFIX to define their own. Add GPL commment to internal.h while we are there. This does not change any actual console output, asside from a whitespace fix. Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA: Major update for acpi_get_object_info external interface Completed a major update for the acpi_get_object_info external interface. Changes include: - Support for variable, unlimited length HID, UID, and CID strings - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) - Call the _SxW power methods on behalf of a device object - Determine if a device is a PCI root bridge - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. These changes will require an update to all callers of this interface. See the ACPICA Programmer Reference for details. Also, update all invocations of acpi_get_object_info interface Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels As of version 2.0, ACPI can return 64-bit integers. The current acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms. Change the argument to take a pointer to an acpi_integer so we support 64-bit integers on all platforms. lenb: replaced use of "acpi_integer" with "unsigned long long" lenb: fixed bug in acpi_thermal_trips_update() Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

ACPI: convert to sysfs framework Setup new sysfs framework 1. Remove /sys/firmware/acpi 2. Add ACPI device in device tree. File "eject" for every device that has _EJ0 method is moved from /sys/firmware to /sys/devices. Operation on this file is exactly the same as before. i.e. echo 1 to "eject" will cause hot removal of this device. Corresponding changes should be made in userspace for hot removal.

[PATCH] acpi bridge hotadd: Allow ACPI .add and .start operations to be done independently Create new interfaces to recursively add an acpi namespace object to the acpi device list, and recursively start the namespace object. This is needed for ACPI based hotplug of a root bridge hierarchy where the add operation must be performed first and the start operation must be performed separately after the hot-plugged devices have been properly configured.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
