Thus, in order to invalidate those when PTE pages are deleted,\nwe need the virtual address to pass to tlbilx or tlbivax instructions.\n\nThe old trick of sticking it somewhere in the PTE page struct page sucks\ntoo much, the address is almost readily available in all call sites and\nalmost everybody implemets these as macros, so we may as well add the\nargument everywhere.
