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.
That seems like a good way of handling it. As archs add their implementations, they can just add the symlink and do no more work. It will also make review slightly easier: if I don't see the symlink added, I'll know the submitter didn't actually test their chacha :-P.
I'll take this into my random.git tree now as a fix.
