commit a5b8ca97fbf8 ("arm64: do not descend to vdso directories twice") changes the cleaning behavior of arm64's vdso files, in that vdso.lds, vdso.so, and vdso.so.dbg are not removed upon a 'make clean/mrproper':

$ make defconfig ARCH=arm64 $ make ARCH=arm64 $ make mrproper ARCH=arm64 $ git clean -nxdf Would remove arch/arm64/kernel/vdso/vdso.lds Would remove arch/arm64/kernel/vdso/vdso.so Would remove arch/arm64/kernel/vdso/vdso.so.dbg

To remedy this, manually descend into arch/arm64/kernel/vdso upon cleaning.

After this commit: $ make defconfig ARCH=arm64 $ make ARCH=arm64 $ make mrproper ARCH=arm64 $ git clean -nxdf <empty>

Similar results are obtained for the vdso32 equivalent.
