...acro is doing in following: /* Hypercall interfaces operate in PFNs for HVM guests * and MFNs for PV guests */ if ( hvm ) pfn_type[batch] = n; else pfn_type[batch] = pfn_to_mfn(n); if ( !is_mapped(pfn_type[batch]) ) { /* ** not currently in psuedo-physical map -- set bit ** in to_fix since we must send this page in last_iter ** unless its sent sooner anyhow, or it never enters ** pseudo-physical map (e.g. for ballooned down doms) */ set_bit(n, to_fix); continue; } This chunk of code makes sense for saving PV domains. The is_mapped() function checks the MSB...
