Some time ago it turned out that our suspend code ordering broke some NVidia-based systems that hung if _PTS was executed with one of the PCI devices, specifically a USB controller, in a low power state. Then, it was noticed that the suspend code ordering was not compliant with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and it was argued that the code had to be changed for that reason (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). So we did, but evidently we did wrong, because it's now turning out that some systems have been broken by this change. Refs: http://bugzilla.kernel.org/show_bug.cgi?id=10340 https://bugzilla.novell.com/show_bug.cgi?id=374217#c16 [ I said at that time that something like this might happend, but the majority of people involved thought that it was improbable due to the necessity to preserve the compliance of hardware with ACPI 1.0. ] This actually is a quite serious regression from 2.6.24. Moreover, the ACPI 1.0 ordering of suspend code introduced another issue that I have only noticed recently. Namely, if the suspend of one of devices fails, the already suspended devices will be resumed without executing _WAK before, which leads to problems on some systems (for example, in such situations thermal management is broken on my HP nx6325). Consequently, it also breaks suspend debugging on the affected systems. Note also, that the requirement to execute _PTS before suspending devices does not really make sense, because the device in question may be put into a low power state at run time for a reason unrelated to a system-wide suspend. For the reasons outlined above, the change of the suspend ordering should be reverted, which is done by the patch below. [ Felix Möller: "I am the reporter from the original Novell Bug: https://bugzilla.novell.com/show_bug.cgi?id=374217 I just tried current git head (two hours ago) with the patch (the one from the beginning of this thread) from Rafael and without it. With the patch my MacBook does suspend without it does not." ] Signed-off-by:

Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from parport IRQ handler), the latter enables interrupts without parport subsystem IRQ handler expecting it. The bug can be seen if you compile kernel with lock dependency checking and use plip --- it produces a warning. This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that it doesn't enable interrupts when already disabled. Signed-off-by: -

Recent driver core change causes references to parent devices being dropped early, at device_del() time, as opposed to when all children are freed. This causes oops in evdev with grabbed devices. Take the reference to the parent input device ourselves to ensure that it stays around long enough. Signed-off-by:Dmitry Torokhov <dtor@mail.ru>

It appears that we can't just check to see if we're in a task context ... so instead of trying that, just make the relevant leds always schedule a little worklet. Signed-off-by:

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix. Signed-off-by:

When getting disconnected we need to release eventual grabs on the underlying input device as we also release the input device itself. Otherwise, we would try to release the grab when the client that requested it closes its handle, accessing the input device which might already be freed. Signed-off-by:

This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors. It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.
