* PM: Warn if interrupts are enabled during suspend-resume of sysdevsRafael J. Wysocki2009-06-12
| | | | | | | | | Sysdevs have to be suspended and resumed with interrupts disabled and things usually break in a way that's difficult to debug if one of sysdev drivers enables interrupts by mistake during suspend or resume. Add extra checks that will generate warnings in such cases. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

* | PM: Rework handling of interrupts during suspend-resumeRafael J. Wysocki2009-03-30
|/ | | | | | | | | | | | | | | | | | | | Use the functions introduced in by the previous patch, suspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(), to rework the handling of interrupts during suspend (hibernation) and resume. Namely, interrupts will only be disabled on the CPU right before suspending sysdevs, while device drivers will be prevented from receiving interrupts, with the help of the new helper function, before their "late" suspend callbacks run (and analogously during resume). In addition, since the device interrups are now disabled before the CPU has turned all interrupts off and the CPU will ACK the interrupts setting the IRQ_PENDING bit for them, check in sysdev_suspend() if any wake-up interrupts are pending and abort suspend if that's the case.

* sysdev: Add utility functions for simple int/ulong variable sysdev attributesAndi Kleen2008-07-22
| | | | | | | | | | | | | This adds a new sysdev_ext_attribute that stores a pointer to the variable it manages and some utility functions/macro to easily use them. Previously all users wrote custom macros to generate show/store functions for each variable, with this it is possible to avoid that in many cases.

* sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-22
| | | | | | | | | | | | | | | | | | | | | | This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections.

* sysdev: fix debugging statements in registration code.Ben Dooks2008-07-22
| | | | | | | | | | | | | | | | | | | | | The systdev_class_register() and sysdev_register() functions have pr_debug() statements which are enabled when the user selects the driver core debug. Both of these routines do not produce the correct output, as they make assumptions about data which has not been initialised. In sysdev_class_register() the code uses the kobject_name(&cls->kset.kobj) at the start of the function, but this is not setup until later in the same call. Change this to use cls->name which is passed in from the caller. The sysdev_register() function tries to get the name of the sysdev by kobject_name(&sysdev->kobj), but that isn't setup until later in the same function so change this message to use the name of the sysdev's class and add another message once the name is initialised.

* sysdev: detect multiple driver registrationsBen Dooks2008-04-19
| | | | | | | | | | | | | | | | I've just found how easy it is to accidentally register a sysdev_driver for two different classes. When this happens, bad things happen as the sysdev_driver structure keeps has the list entry for the driver registration. The following patch makes a WARN_ON() if this happens, although I think BUG_ON or returning -EAGAIN could also be valid responses to this.

* sysdev: remove global sysdev drivers listAkinobu Mita2007-10-12
| | | | | | | | | | | | | | | | | | | No one uses sysdev_drivers. Because no one calls sysdev_driver_register with NULL class.

* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

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!
