[Xen-devel] [PATCH] xen/pt: Don't slurp wholesale the PCI configuration registers

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Instead we have the emulation registers ->init functions which
consult the host values to see what the initial value should be
and they are responsible for populating the dev.config.
