Indeed, but the !CONFIG_PARAVIRT variant paravirt_tlb_remove_table() 
however calls tlb_remove_page().

tlb_remove_page() ends up in 
__tlb_remove_page_size()->__tlb_remove_folio_pages_size(), not in 
tlb_remove_table()

... but maybe I am looking at the wrong tree, so I wonder if this is 
okay an simply not spelled out here explicitly?
