    kernel: Port new device_pager interface from FreeBSD

should probably be amended in sys/vm/device_pager.c, function 
old_dev_pager_fault() to use

paddr = pmap_phys_address(
    dev_dmmap(dev, offset << PAGE_SHIFT, prot));

similar to what had been used in the previous version of dev_pager_getpage().

Without this change, legacy drm systems running say a Radeon 4xxx graphics card 
failed to have dports Xorg start.
