This is from a patch that was posted in the memtest86+ forum:

The patch also included some unrelated changes to get_key()
which I have removed.

Subject: [PATCH 7/8] rewrite popup popdown popclear

merge popup and pop2up
merge popdown and pop2down
merge popclear and pop2clear

"It merge popup and pop2up, popdown and pop2down, popclear and
pop2clear. So when you change popup you don't have to change
pop2up anymore… it's less risky."
