Sometimes the stream may be stopped due to XRUN events, in which case the userspace can call snd_pcm_drop() and snd_pcm_prepare() to stop and start the stream again.

In these cases, we must wait for the DMA channel to synchronize before marking the stream as prepared for playback, as the DMA channel gets stopped by drop() without any synchronization. Make sure the ALSA core synchronizes the DMA channel by adding a sync_stop() hook.

The rfkill hotkey handling is already provided by the wireless-hotkey driver. Remove the now unnecessary rfkill hotkey handling to avoid duplicating functionality.

The ACPI notify handler still prints debugging information when receiving ACPI notifications to aid in reverse-engineering.

On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped under \XINI, but instead are mapped under _SB.XINI.

The reason for this is that the LGEX0820 ACPI device used by this driver is mapped at _SB.XINI, so the ACPI methods where moved as well to appear below the LGEX0820 ACPI device.

Fix this by using the ACPI handle from the ACPI device when evaluating both methods.

[ Upstream commit 403f17a330732a666ae793f3b15bc75bb5540524 ]

The sys_fanotify_mark() syscall on parisc uses the reverse word order for the two halves of the 64-bit argument compared to all syscalls on all 32-bit architectures. As far as I can tell, the problem is that the function arguments on parisc are sorted backwards (26, 25, 24, 23, ...) compared to everyone else, so the calling conventions of using an even/odd register pair in native word order result in the lower word coming first in function arguments, matching the expected behavior on little-endian architectures. The system call conventions however ended up matching what the other 32-bit architectures do.

A glibc cleanup in 2020 changed the userspace behavior in a way that handles all architectures consistently, but this inadvertently broke parisc32 by changing to the same method as everyone else.

The change made it into glibc-2.35 and subsequently into debian 12 (bookworm), which is the latest stable release. This means we need to choose between reverting the glibc change or changing the kernel to match it again, but either hange will leave some systems broken.

Pick the option that is more likely to help current and future users and change the kernel to match current glibc. This also means the behavior is now consistent across architectures, but it breaks running new kernels with old glibc builds before 2.35.

The alternative is to fix this by reverting glibc back to the unusual behavior.
