One question on MMIO
In sh_page_fault(), there are some code like following, why we think it
is mmio only when paging_vcpu_mode_translate(v)?
Thanks

/* What mfn is the guest trying to access? */
gfn = guest_l1e_get_gfn(gw.eff_l1e);
gmfn = vcpu_gfn_to_mfn(v, gfn);
mmio = (is_hvm_domain(d)
&& paging_vcpu_mode_translate(v)
&& mmio_space(gfn_to_paddr(gfn)));
if...
