Saruman (where he went)

[Iarephelion]

Unfinished Tales p. 391

Whereas Curunir was cast down, and utterly humbled, and perished at last by the hand of an oppressed slave;and his spirit went whithersoever it was doomed to go, and to Middle Earth,whether naked or embodied, came never back.

It is not stated here where Saruman's spirit wound up but it was not Middle Earth nor is it likely he went back into the West. It is also said on the previous page that the memory of the Blessed Realm (Valinor) remained while the Istari were true to their purpose. This implies that those who lost their way (arguably including Radagast) also lost the knowledge of whence they had come.
