    [PATCH] i386: PARAVIRT: Allocate a fixmap slot
    Allocate a fixmap slot for use by a paravirt_ops implementation.  This
    is intended for early-boot bootstrap mappings.  Once the zones and
    allocator have been set up, it would be better to use get_vm_area() to
    allocate some virtual space.
    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.  It is needed early because it contains the vcpu state,
    including the interrupt mask.
