That won't work because this is a rebase branch, meaning that EVL sits
on top of the mainline tip, therefore #e6edaf26 is below the first
commit introducing the EVL code.

There are several ways to do this, but in your case, the easiest would
be to check out this tag: v5.10.83-evl1-rebase. There is no additional
EVL code between v5.10.83-evl1-rebase and v5.10.99-evl1-rebase.
