    page-flags: define behavior of Xen-related flags on compound pages · c13985fa

    PG_pinned and PG_savepinned are about page table's pages which are never
    compound.
    
    I'm not so sure about PG_foreign, but it seems we shouldn't see compound
    pages there too.
    
    Let's use PF_NO_COMPOUND for all of them.
