The tlb index and entry are often retrieved together and tlb_entry()

The compiler does a good job removing duplicate calculations already.
What effect do you see with this?
Hard to tell because measurements always change slightly when I run some
benchmark in guest so if it has an effect it's not big but I find it more
readable with a single call than two calls so that's the main motivation
here.
