From 83d08f2673504a299194dcac1657a13754b5932a Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 29 Oct 2013 13:57:34 +0100 Subject: pc: map PCI address space as catchall region for not mapped addresses With a help of negative memory region priority PCI address space is mapped underneath RAM regions effectively catching every access to addresses not mapped by any other region. It simplifies PCI address space mapping into system address space. Signed-off-by: Michael S.
