From 6bb40e81b938beb53eb4102cdfae03dd79edbf13 Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Thu, 9 Oct 2008 14:46:16 +0100 Subject: [PATCH] [ia64] Fix memory size calculation on VT-i over 3GB memory VT-i domains have two memory holes: VGA I/O (under 1MB) and MMIO (3GB-4GB). This patch calculates the correct memory size with them. This is based on xen-unstable 10936:a0b3cf802d99.
