linux-alpha, linux-arch, linux-arm-kernel, linux-mips, linux-mm, linux-riscv, linux-s390, linux-sh, lkml, loongarch, sparclinux
Subsystem:
generic include/asm header files, the rest · Maintainers:
Arnd Bergmann, Linus Torvalds
Upcoming changes will create architecture-specific asm/auxvec.h headers. Add asm-generic infrastructure to handle the fallbacks for architectures which are not migrated yet and those which won't require their own definition. Extend the list of includes in linux/auxvec.h to cover all potential low-level auxvec.h headers.
