The next four patches are directly related to fixing the kexec path. These patches cause xen to track the BSP local APIC boot state and return to it before kexec'ing to a new kernel. This prevents the kdump kernel falling over itself when booting in x2apic mode while expecting to be in xapic mode. It also makes sure to disable IO virtualisation, along with fixing the current codepath related to disabling Interrup Remapping on Intel VTD boxes. Signed-off-by: Andrew Cooper
