From 8502a2cdcc61542930b25ea3e4261cf4bf3b1a41 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Wed, 16 Oct 2019 12:12:51 +0100 Subject: [PATCH] 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.
