Hi,

This series implements the core parts of Xen dom0 support; that is, just
enough to get the kernel started when booted by Xen as a dom0 kernel.

The Xen dom0 kernel runs as a normal paravirtualized Xen kernel, but
it also has the additional responsibilty for managing all the machine's
hardware, as Xen itself has almost no internal driver support (it barely
even knows about PCI).

This series includes:
 - setting up a Xen hvc console
 - initializing Xenbus
 - enabling IO permissions for the kernel
 - MTRR setup hooks
 - Use _PAGE_IOMAP to allow direct hardware mappings
 - add a paravirt-ops for page_is_ram, to allow Xen to exclude granted pages
 - enable the use of a vga console

Not included in this series is the hooks into apic setup; that's next.

This may be pulled from:
