powerpc: Remove arch-specific strncpy() implementation

2026-06-18T23:37:13+00:00

strncpy() has no remaining callers in the kernel[1]. Remove the powerpc-specific assembly implementation from both the kernel (arch/powerpc/lib/string.S) and the boot wrapper (arch/powerpc/boot/string.S), along with the __HAVE_ARCH_STRNCPY define and declaration, falling back to the generic version in lib/string.c. The boot wrapper's strncpy had no callers in arch/powerpc/boot/. Link: https://github.com/KSPP/linux/issues/90 [1] Signed-off-by: Kees Cook

powerpc/boot: Allow text relocations for pseries wrapper with binutils 2.46+

2026-06-15T10:54:07+00:00

Binutils 2.46 changed the default linker behavior from '-z notext' to '-z text', which treats dynamic relocations in read-only segments as errors rather than warnings. This causes the pseries boot wrapper build to fail with: /usr/bin/ld.bfd: arch/powerpc/boot/wrapper.a(crt0.o): warning: relocation against `_platform_stack_top' in read-only section `.text' /usr/bin/ld.bfd: error: read-only segment has dynamic relocations The pseries wrapper uses '-pie' to create position-independent code. However, crt0.S contains a pointer to '_platform_stack_top' in the .text section, which requires a dynamic relocation at runtime. This creates DT_TEXTREL (text relocations), which were allowed by default in binutils 2.45 and earlier (via implicit '-z notext') but are now rejected by binutils 2.46+. Add '-z notext' linker flag to explicitly allow text relocations for the pseries platform, similar to what is already done for the epapr platform. This restores the previous behavior and allows the boot wrapper to build successfully with binutils 2.46+.

powerpc: Fix indentation and replace typedef with struct name

2026-06-02T05:54:33+00:00

Indent several struct members using tabs instead of spaces. Replace the typedef alias AOUTHDR with an explicit struct name to silence a checkpatch warning. Signed-off-by: Thorsten Blum Signed-off-by: Madhavan Srinivasan Link: https://patch.msgid.link/20250517125834.421088-2-thorsten.blum@linux.dev

powerpc: dts: Build devicetrees of enabled platforms

2026-06-02T05:29:36+00:00

Follow the same approach as other architectures such as Arm or RISC-V, and build devicetrees based on platforms selected in Kconfig. This makes it unnecessary to use CONFIG_OF_ALL_DTBS on PowerPC in order to build DTB files. This makes it easier to use other build and test infrastructure such as `make dtbs_check`, and is a first step towards generating FIT images that include all the relevant DTBs with `make image.fit`.

powerpc: dts: Add missing model properties

2026-06-02T05:28:27+00:00

These are the remaining PowerPC devicetrees that do not have a /model property, even though it is required by the devicetree specification. Fix them by simply copying the compatible string.
