2025-04-04ARM: sa1100/assabet: remove PWER initialisationRussell King
Remove the explicit PWER initialisation: gpio-keys already enables wake-up for its keys, and so this setting is redundant. In any case, the conversion of the SA1100 GPIOs to gpiolib has made this setting ineffectual. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2025-04-04ARM: sa1100: switch to accurate MPLL calculationRussell King
Switch SA1100 to the more accurate MPLL calculation. Table 8-1 in the SA1110 developers manual gives two sets of frequencies for two different crystals - 3.6864MHz and 3.5795MHz. Calculating the multiplication factor for each entry in the table shows that the clock rates given are are equal to the crystal frequency multiplied by 4(4 + PPCR), rounded to 100kHz. This equation holds for the higher frequencies up to 280.2MHz which have been omitted from the later manuals. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2025-04-04ALSA: ASoC: add generic slave and cyclic DMA engine supportRussell King
Add a generic DMA engine platform driver to ASoC. This allows a range of DMA engines to be used to transfer data to a CPUs audio interface without having to rewrite this code many times. This driver supports both DMA_SLAVE and DMA_CYCLIC channels, preferring DMA_CYCLIC channels over DMA_SLAVE channels. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2025-04-04ALSA: ASoC: fix generic dmaengine channel requestingRussell King
The ASoC generic dmaengine support takes a filter data parameter via struct snd_dmaengine_dai_dma_data. However, rather than passing the filter data to the DMA engine request function, it passed the struct snd_dmaengine_dai_dma_data itself. Fix this.

2025-03-22keys: Fix UAF in key_put()David Howells
Once a key's reference count has been reduced to 0, the garbage collector thread may destroy it at any time and so key_put() is not allowed to touch the key after that point. The most key_put() is normally allowed to do is to touch key_gc_work as that's a static global variable. However, in an effort to speed up the reclamation of quota, this is now done in key_put() once the key's usage is reduced to 0 - but now the code is looking at the key after the deadline, which is forbidden. Fix this by using a flag to indicate that a key can be gc'd now rather than looking at the key's refcount in the garbage collector.

2025-03-22perf/amd/ibs: Prevent leaking sensitive data to userspaceNamhyung Kim
Although IBS "swfilt" can prevent leaking samples with kernel RIP to the userspace, there are few subtle cases where a 'data' address and/or a 'branch target' address can fall under kernel address range although RIP is from userspace. Prevent leaking kernel 'data' addresses by discarding such samples when {exclude_kernel=1,swfilt=1}. IBS can now be invoked by unprivileged user with the introduction of "swfilt". However, this creates a loophole in the interface where an unprivileged user can get physical address of the userspace virtual addresses through IBS register raw dump (PERF_SAMPLE_RAW). Prevent this as well. This upstream commit fixed the most obvious leak: 65a99264f5e5 perf/x86: Check data address for IBS software filter Follow that up with a more complete fix.
