This adds a const to the definitions vvar.c makes, so that the vdso_* variables go into .rodata instead of .data. This is essentially a cosmetic change, just giving the section headers in the vDSO file more pleasing flags. These variables are read-only from the perspective of the vDSO itself and user mode, even though the contents of the DSO image were adjusted at boot.
