> Mainline moved sparc to the generic vDSO library in 7c5fc16c7a56
> ("sparc64: vdso: Switch to the generic vDSO library") before it let
> TIME_NS go without the vDSO; this kernel has not, and its sparc vDSO
> knows nothing of the offsets, so a task in a time namespace would read
> host time from it and namespace time from the syscall. Keep the option
> off where a vDSO updates its own time data without the generic library,
> sparc here. x86_64 and arm64 keep it, and User Mode Linux, which has no
