Every user of the VM_SPECIAL or VMA_SPECIAL_FLAGS has now been converted to predicates which explicitly express what is actually being checked for rather than the nebulous concept of possessing 'special' VMA flags.
In any case 'special' is not so special a term of art in mm - it includes VDSO/VVAR mappings, special in the sense of vm_normal_folio() and probably other cases too. Therefore make things less special by eliminating these now unused flags. No functional change intended.
