This patch series implements the Linux Xen guest in terms of the
paravirt-ops interface. The features in implemented this patch series

Allocate a fixmap slot for use by a paravirt_ops implementation. Xen
uses this to map the hypervisor's shared info page, which doesn't have
a pseudo-physical page number, and therefore can't be mapped

1) Can any one please shed some light on precisely and exactly what are
differences in different boards for which we need to port linux?
The differences depends on the boards ... Mostly if they belong to the
