[Xen-devel] [patch 07/24] Xen-paravirt_ops: paravirt_ops: allocate a fixmap slot

[Jeremy Fitzhardinge <jeremy@xxxxxxxx>]

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
ordinarily.
