The mips vDSO library requires some adaptations to take advantage of the newly introduced generic vDSO library. Introduce the following changes: - Modification of vdso.c to be compliant with the common vdso datapage - Use of lib/vdso for gettimeofday Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Paul Burton <paul.burton@mips.com> Signed-off-by: Vincenzo Frascino <vincenzo.frascino@arm.com> [paul.burton@mips.com: Prepend $(src) to config-n32-o32-env.c path.] Signed-off-by: Paul Burton <paul.burton@mips.com>
