Notice that clearing these bits does not always take away the corresponding permissions (for example, permission is granted when the bit is cleared). The bits are cleared but are to be set or left cleared accordingly in pmap_set_prot(), pmap_enter_locked(), etc. Clear L2_XN along with L2_S_PROT_MASK in pmap_set_prot() so that all permissions related bits are cleared before actual configuration.
