Actually there are TWO places, but they don't interfere:
1) exit to user
2) enter guest
From the kernel POV they are pretty much the same as both are leaving the kernel domain. But they have a few subtle different requirements what has to be done or not.
So any change to that logic needs to fixup both places,
