commit 08e2059facd78d5ffaf206ba06ac2017c4adeed4 Author: Julien Grall <julien.grall@xxxxxxx> AuthorDate: Wed Oct 16 12:12:51 2019 +0100 Commit: Julien Grall <julien.grall@xxxxxxx> CommitDate: Tue Oct 22 17:56:22 2019 +0100 xen/arm: setup: Calculate correctly the size of Xen The current size of Xen is computed using _end - _start + 1. However, _end is pointing one past the end of Xen, so the size of Xen is off-by-one.
