The question is why instead of reimplement each x32 syscall call that
requires long long return with specific arch implementations (this
very patch idea) we change the x32 syscall return to long long
instead?
So instead of redefine each INTERNAL_SYSCALL_XXX for x32 we make it
work on the current times implementation instead.
