Now that all callers have been replaced with snd_device_register_for_dev(), let's drop the obsolete device registration code and concentrate only on the code handling struct device directly. That said, - remove the old snd_device_register(), - rename snd_device_register_for_dev() with snd_device_register(), - drop superfluous arguments from snd_device_register(), - change snd_unregister_device() to pass the device pointer directly Reviewed-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Like previous patches, this one embeds the struct device into struct snd_compr. As the dev field wasn't used beforehand, it's reused as the new device struct. Reviewed-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Like previous patches, this changes the device management for rawmidi, embedding the struct device into struct snd_rawmidi. The required change is more or less same as hwdep device. The currently unused dev field is reused as the new embedded struct field now. Reviewed-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Like previous patches, at this time we embed the struct device into PCM object. However, this needs a bit more caution: struct snd_pcm doesn't own one device but two, for both playback and capture! Thus not struct snd_pcm but struct snd_pcm_str object contains the device. Along with this change, pcm->dev field is dropped for avoiding confusion. It was meant to point to a non-standard parent. But, since now we can touch each struct device directly, we can manipulate the parent field easily there, too.

Like the previous patch, this one embeds the device object into hwdep object. For a proper object lifecycle, it's freed in the release callback. This also allows us to create sysfs entries via passing to the groups field of the device without explicit function calls. Since each driver can see the device and touch its groups field directly, we don't need to delegate in hwdep core any longer. So, remove the groups field from snd_hwdep, and let the user (in this case only hda_hwdep.c) modify the device groups.

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report on nested sleep conditions, which we generally want to avoid because the inner sleeping operation can re-set the thread state to TASK_RUNNING, but that will then cause the outer sleep loop not actually sleep when it calls schedule. However, that's actually valid traditional behavior, with the inner sleep being some fairly rare case (like taking a sleeping lock that normally doesn't actually need to sleep). And the debug code would actually change the state of the task to TASK_RUNNING internally, which makes that kind of traditional and working code not work at all, because now the nested sleep doesn't just sometimes cause the outer one to not block, but will cause it to happen every time. In particular, it will cause the cardbus kernel daemon (pccardd) to basically busy-loop doing scheduling, converting a laptop into a heater, as reported by Bruno Prémont. But there may be other legacy uses of that nested sleep model in other drivers that are also likely to never get converted to the new model. This fixes both cases: - don't set TASK_RUNNING when the nested condition happens (note: even if WARN_ONCE() only _warns_ once, the return value isn't whether the warning happened, but whether the condition for the warning was true. So despite the warning only happening once, the "if (WARN_ON(..))" would trigger for every nested sleep. - in the cases where we knowingly disable the warning by using "sched_annotate_sleep()", don't change the task state (that is used for all core scheduling decisions), instead use '->task_state_change' that is used for the debugging decision itself. (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the suggested change to use 'task_state_change' as part of the test) Reported-and-bisected-by: Bruno Prémont <bonbons@linux-vserver.org> Tested-by: Rafael J Wysocki <rjw@rjwysocki.net> Acked-by: Oleg Nesterov <oleg@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de>, Cc: Ilya Dryomov <ilya.dryomov@inktank.com>, Cc: Mike Galbraith <umgwanakikbuti@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Hurley <peter@hurleysoftware.com>, Cc: Davidlohr Bueso <dave@stgolabs.net>, Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When handling a fault in stage-2, we need to resync I$ and D$, just to be sure we don't leave any old cache line behind. That's very good, except that we do so using the *user* address. Under heavy load (swapping like crazy), we may end up in a situation where the page gets mapped in stage-2 while being unmapped from userspace by another CPU. At that point, the DC/IC instructions can generate a fault, which we handle with kvm->mmu_lock held. The box quickly deadlocks, user is unhappy. Instead, perform this invalidation through the kernel mapping, which is guaranteed to be present. The box is much happier, and so am I.

Let's assume a guest has created an uncached mapping, and written to that page. Let's also assume that the host uses a cache-coherent IO subsystem. Let's finally assume that the host is under memory pressure and starts to swap things out. Before this "uncached" page is evicted, we need to make sure we invalidate potential speculated, clean cache lines that are sitting there, or the IO subsystem is going to swap out the cached view, loosing the data that has been written directly into memory.
