2025-03-07media: platform: synopsys: hdmirx: Fix 64-bit division for 32-bit targetsNathan Chancellor
The build fails for 32-bit targets with: arm-linux-gnueabi-ld: drivers/media/platform/synopsys/hdmirx/snps_hdmirx.o: in function `hdmirx_get_timings': snps_hdmirx.c:(.text.hdmirx_get_timings+0x46c): undefined reference to `__aeabi_uldivmod' bt->pixelclock is __u64, which causes the compiler to emit a libcall for 64-bit division. Use the optimized kernel helper, div_u64(), to resolve this.

2025-03-07irqchip/sunxi-nmi: Support Allwinner A523 NMI controllerAndre Przywara
The NMI controller in the Allwinner A523 is almost compatible to the previous versions of this IP, but requires the extra bit 31 to be set in the enable register to actually report the NMI. Add a mask to allow such an enable bit to be specified, and add this to the per-SoC data structure. As this struct was just for different register offsets so far, it was consequently named "reg_offs", which is now no longer applicable, so rename this to the more generic "data" on the way, and move the existing offsets into a struct of its own. Also add the respective Allwinner A523 compatible string, and set bit 31 in its enable mask, to add support for this SoC.

2025-03-07mtd: spi-nor: explicitly include <linux/math64.h>Tudor Ambarus
swp and otp drivers use div_u64 and div64_u64 and rely on implicit inclusion of <linux/math64.h>. It is good practice to directly include all headers used, it avoids implicit dependencies and spurious breakage if someone rearranges headers and causes the implicit include to vanish. Include the missing header.

2025-03-06fs/pipe: add simpler helpers for common casesLinus Torvalds
The fix to atomically read the pipe head and tail state when not holding the pipe mutex has caused a number of headaches due to the size change of the involved types. It turns out that we don't have _that_ many places that access these fields directly and were affected, but we have more than we strictly should have, because our low-level helper functions have been designed to have intimate knowledge of how the pipes work. And as a result, that random noise of direct 'pipe->head' and 'pipe->tail' accesses makes it harder to pinpoint any actual potential problem spots remaining. For example, we didn't have a "is the pipe full" helper function, but instead had a "given these pipe buffer indexes and this pipe size, is the pipe full". That's because some low-level pipe code does actually want that much more complicated interface. But most other places literally just want a "is the pipe full" helper, and not having it meant that those places ended up being unnecessarily much too aware of this all. It would have been much better if only the very core pipe code that cared had been the one aware of this all. So let's fix it - better late than never. This just introduces the trivial wrappers for "is this pipe full or empty" and to get how many pipe buffers are used, so that instead of writing if (pipe_full(pipe->head, pipe->tail, pipe->max_usage)) the places that literally just want to know if a pipe is full can just say if (pipe_is_full(pipe)) instead. The existing trivial cases were converted with a 'sed' script. This cuts down on the places that access pipe->head and pipe->tail directly outside of the pipe code (and core splice code) quite a lot. The splice code in particular still revels in doing the direct low-level accesses, and the fuse fuse_dev_splice_write() code also seems a bit unnecessarily eager to go very low-level, but it's at least a bit better than it used to be.

Also, use a "explicit typecast + clamp" instead of just a "clamp_t" as the latter typecasts first and then clamps between the limits, which defeats our purpose.

2025-03-06media: vivid: Move all fb_info references into vivid-osdRicardo Ribalda
Most references to fb_info are already within vivid-osd.c. This patch moves the remaining references into vivid-osd.c. We also take this opportunity to make the function names in vivid-osd more consistent. This is a preparation patch to make CONFIG_FB optional for vivid.

2025-03-06media: qcom: Clean up Kconfig dependenciesRobin Murphy
Depending on IOMMU_DMA is suspicious, since the low-level DMA ops internals and MSI helpers is provides are not of interest to general drivers. In practice it mostly seems to be serving as a dependency on ARM64 here, so do that properly. The venus driver looks like it won't actually be useful at runtime without the IOMMU API, so add that too.

In v4l2_detect_gtf(), it seems safer to cast the 32-bit image_width variable to the 64-bit type u64 before multiplying to avoid a possible overflow. The resulting object code even seems to look better, at least on x86_64. Found by Linux Verification Center (linuxtesting.org) with Svace.
