Subject: paravirt_ops: Allocate a fixmap slot
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
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.
