Subsystem:
generic vdso library, kernel selftest framework, the rest · Maintainers:
Andy Lutomirski, Thomas Gleixner, Vincenzo Frascino, Shuah Khan, Linus Torvalds
Architectures use different location for vDSO sources: arch/mips/vdso arch/sparc/vdso arch/arm64/kernel/vdso arch/riscv/kernel/vdso arch/csky/kernel/vdso arch/x86/um/vdso arch/x86/entry/vdso arch/powerpc/kernel/vdso arch/arm/vdso arch/loongarch/vdso Don't hard-code vdso sources location in selftest Makefile, instead create a vdso/ symbolic link in tools/arch/$arch/ and update Makefile accordingly.
