2025-09-25arch: Add the macro COMPILE_OFFSETS to all the asm-offsets.cMenglong Dong
The include/generated/asm-offsets.h is generated in Kbuild during compiling from arch/SRCARCH/kernel/asm-offsets.c. When we want to generate another similar offset header file, circular dependency can happen. For example, we want to generate a offset file include/generated/test.h, which is included in include/sched/sched.h. If we generate asm-offsets.h first, it will fail, as include/sched/sched.h is included in asm-offsets.c and include/generated/test.h doesn't exist; If we generate test.h first, it can't success neither, as include/generated/asm-offsets.h is included by it. In x86_64, the macro COMPILE_OFFSETS is used to avoid such circular dependency. We can generate asm-offsets.h first, and if the COMPILE_OFFSETS is defined, we don't include the "generated/test.h". And we define the macro COMPILE_OFFSETS for all the asm-offsets.c for this purpose. Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>

pci-legacy.c under MIPS has a copy of pci_enable_resources() named as pcibios_enable_resources(). Having own copy of same functionality could lead to inconsistencies in behavior, especially now as pci_enable_resources() and the bridge window resource flags behavior are going to be altered by upcoming changes. The check for !r->start && r->end is already covered by the more generic checks done in pci_enable_resources(). Call pci_enable_resources() from MIPS's pcibios_enable_device() and remove pcibios_enable_resources().

2025-09-13mm: introduce memdesc_flags_tMatthew Wilcox (Oracle)
Patch series "Add and use memdesc_flags_t". At some point struct page will be separated from struct slab and struct folio. This is a step towards that by introducing a type for the 'flags' word of all three structures. This gives us a certain amount of type safety by establishing that some of these unsigned longs are different from other unsigned longs in that they contain things like node ID, section number and zone number in the upper bits. That lets us have functions that can be easily called by anyone who has a slab, folio or page (but not easily by anyone else) to get the node or zone. There's going to be some unusual merge problems with this as some odd bits of the kernel decide they want to print out the flags value or something similar by writing page->flags and now they'll need to write page->flags.f instead. That's most of the churn here. Maybe we should be removing these things from the debug output? This patch (of 11): Wrap the unsigned long flags in a typedef. In upcoming patches, this will provide a strong hint that you can't just pass a random unsigned long to functions which take this as an argument.

2025-09-08mips: Add __attribute_const__ to ffs()-family implementationsKees Cook
While tracking down a problem where constant expressions used by BUILD_BUG_ON() suddenly stopped working[1], we found that an added static initializer was convincing the compiler that it couldn't track the state of the prior statically initialized value. Tracing this down found that ffs() was used in the initializer macro, but since it wasn't marked with __attribute__const__, the compiler had to assume the function might change variable states as a side-effect (which is not true for ffs(), which provides deterministic math results). Add missing __attribute_const__ annotations to MIPS's implementations of ffs(), __ffs(), fls(), and __fls() functions. These are pure mathematical functions that always return the same result for the same input with no side effects, making them eligible for compiler optimization.

2025-09-01arch: copy_thread: pass clone_flags as u64Simon Schuster
With the introduction of clone3 in commit 7f192e3cd316 ("fork: add clone3") the effective bit width of clone_flags on all architectures was increased from 32-bit to 64-bit, with a new type of u64 for the flags. However, for most consumers of clone_flags the interface was not changed from the previous type of unsigned long. While this works fine as long as none of the new 64-bit flag bits (CLONE_CLEAR_SIGHAND and CLONE_INTO_CGROUP) are evaluated, this is still undesirable in terms of the principle of least surprise. Thus, this commit fixes all relevant interfaces of the copy_thread function that is called from copy_process to consistently pass clone_flags as u64, so that no truncation to 32-bit integers occurs on 32-bit architectures.

Replace memset(0) followed by the deprecated strcpy() with strscpy_pad() to improve octeon_fdt_set_phy(). This avoids zeroing the memory before copying the string and ensures the destination buffer is only written to once, simplifying the code and improving efficiency.

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch appended to the "under-the-cut" portion of the patch. Note that prior to running Coccinelle, alchemy_clk_aux_roundr() was renamed to alchemy_clk_aux_round_rate(). A few minor style cleanups were also done by hand.

2025-08-29mips: Replace __ASSEMBLY__ with __ASSEMBLER__ in the mips headersThomas Huth
While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. Defining such a macro was necessary in the early days of the kernel, since GCC only started providing __ASSEMBLER__ since version 3.0 in 2000 (see https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=f8f769ea4e69 ). However, having two macros can be very confusing nowadays for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with just one comment tweaked manually in arch/mips/include/asm/cpu.h (that was missing some underscores).

2025-08-26net: phy: fixed: let fixed_phy_add always use addr 0 and remove return valueHeiner Kallweit
We have only two users of fixed_phy_add(), both use address 0 and ignore the return value. So simplify fixed_phy_add() accordingly. Whilst at it, constify the fixed_phy_status configs. Note: fixed_phy_add() is a legacy function which shouldn't be used in new code, as it's use may be problematic: - No check whether a fixed phy exists already at the given address - If fixed_phy_register() is called afterwards by any other driver, then it will also use phy_addr 0, because fixed_phy_add() ignores the ida which manages address assignment Drivers using a fixed phy created by fixed_phy_add() in platform code, should dynamically create a fixed phy with fixed_phy_register() instead.
