Is there a reason why we can't have new MT_ types for PAGE_HYP and the HYP MT_DEVICE type (which is the same as MT_DEVICE but with PTE_USER set) and have the standard ARM/generic kernel code build those mappings? That would (it seems) also avoid the need to export the pXd_clear_bad() acessors too... _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
