#     powerpc/vdso32: Fallback on getres syscall when clock is unknown
#     
#     There are other clocks than the standard ones, for instance
#     per process clocks. Therefore, being above the last standard clock
#     doesn't mean it is a bad clock. So, fallback to syscall instead
#     of returning -EINVAL inconditionaly.
#     
#     Fixes: e33ffc956b08 ("powerpc/vdso32: implement clock_getres entirely")
