2026-03-20hwmon: (max6639) Fix pulses-per-revolution implementationGuenter Roeck
The valid range for the pulses-per-revolution devicetree property is 1..4. The current code checks for a range of 1..5. Fix it. Declare the variable used to retrieve pulses per revolution from devicetree as u32 (unsigned) to match the of_property_read_u32() API. The current code uses a postfix decrement when writing the pulses per resolution into the chip. This has no effect since the value is evaluated before it is decremented. Fix it by decrementing before evaluating the value.

2026-03-20check-uapi: honor ${CROSS_COMPILE} settingArnd Bergmann
When ${CROSS_COMPILE} is set, but ${CC} is not set, the logic in check-uapi.sh is different from the top-level Makefile, which defaults to using the cross gcc. This leads to using the native gcc instead of the cross version, resulting in unexpected false-positive and false-negative output. Use the same logic here that we use in Kbuild for consistency.

2026-03-20check-uapi: link into shared objectsArnd Bergmann
While testing ABI changes across all architectures, I found that abidiff sometimes produces nonsensical output. Further debugging identified missing or broken libelf support for architecture specific relocations in ET_REL binaries as the source of the problem[1]. Change the script to no longer produce a relocatable object file but instead create a shared library for each header. This makes abidiff work for all of the architectures in upstream linux kernels.

2026-03-20vfio: selftests: Support DMR and GNR-D DSA devicesYi Lai
Currently, the VFIO DSA driver test only supports the SPR DSA device ID. Attempting to run the test on newer platforms like DMR or GNR-D results in a "No driver found" error, causing the test to be skipped. Refactor dsa_probe() to use a switch statement for checking device IDs. This improves maintainability and makes it easier to add new device IDs in the future.

2026-03-20PM: hibernate: return -ENODATA if the snapshot image is not loadedAlberto Garcia
snapshot_image_loaded() is used in both the in-kernel and the userspace restore path to ensure that the snapshot image has been completely loaded. However the latter path returns -EPERM in such situations, which is meant for cases where the operation is neither write-only nor ready.

2026-03-20init/Kconfig: Require a release version of clang-22 for CC_HAS_COUNTED_BY_PTRNathan Chancellor
Commit 150a04d817d8 ("compiler_types.h: Attributes: Add __counted_by_ptr macro") used Clang 22.0.0 as a minimum supported version for __counted_by_ptr, which made sense while 22.0.0 was the version of LLVM's main branch to allow developers to easily test and develop uses of __counted_by_ptr in their code. However, __counted_by_ptr requires a change [1] merged towards the end of the 22 development cycle to avoid errors when applied to void pointers. In file included from fs/xfs/xfs_attr_inactive.c:18: fs/xfs/libxfs/xfs_attr.h:59:2: error: 'counted_by' cannot be applied to a pointer with pointee of unknown size because 'void' is an incomplete type 59 | void *buffer __counted_by_ptr(bufsize); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is disruptive for deployed prerelease clang-22 builds (such as Android LLVM) or when bisecting between llvmorg-21-init and the fix.

All MIPS ISAs before r6 use the 'lo' and 'hi' special registers. These are clobbered by system calls and need to be marked as such to avoid miscompilations.

2026-03-20selftests/nolibc: Use printf variable field widths and precisionsDavid Laight
Now that printf supports '*' for field widths and precisions then can be used to simplify the test output. - aligning the "[OK]" strings. - reporting the expected sprintf() output when there is a mismatch.

2026-03-20tools/nolibc/printf: Add support for octal outputDavid Laight
Octal output isn't often used, but adding it costs very little. Supporting "%#o" is mildly annoying, it has to add a leading '0' if there isn't one present. In simple cases this is the same as adding a sign of '0' - but that adds an extra '0' in a few places. So you need 3 tests, %o, # and no leading '0' (which can only be checked after the zero pad for precision). If all the test are deferred until after zero padding then too many values are 'live' across the call to _nolibc_u64toa_base() and get spilled to stack. Hence the check that ignores the 'sign' if it is the same as the first character of the output string. Add tests for octal output.

2026-03-20tools/nolibc/printf: Add support for zero padding and field precisionDavid Laight
Includes support for variable field widths (eg "%*.*d"). Zero padding is limited to 31 zero characters. This is wider than the largest numeric field so shouldn't be a problem. All the standard printf formats are now supported except octal and floating point.

2026-03-20tools/nolibc/printf: Special case 0 and add support for %#xDavid Laight
The output for %#x is almost the same as that for %p, both output in hexadecimal with a leading "0x". However for zero %#x should just output "0" (the same as decimal and ocal). For %p match glibc and output "(nil)" rather than "0x0" or "0". Add tests for "%#x", "% d", "%+d" and passing NULL to "%p".

Instead of appending the converted number to the sign, convert first and then prepend the sign (or "0x"). Use the length returned by u64toh_r() instead of calling strlen(). Needed so that zero padding can be inserted between the sign and digits in an upcoming patch.

2026-03-20tools/nolibc/printf: Add support for length modifiers tzqL and formats iXDavid Laight
Length modifiers t (ptrdiff_t) and z (size_t) are aliases for l (long), q and L are 64bit the same as j (intmax). Format i is an alias for d and X similar to x but upper case. Supporting them is mostly just adding the relevant bit to the bit pattern used for matching characters. Although %X is detected the output will be lower case. Change/add tests to use conversions i and X, and length modifiers L and ll. Use the correct minimum value for "%Li".
