DRM cdev pager is not compatible with ARM pmap.

Actually, this is the only problematic part of linux KPI and/or kernel VM. And it need longer clarification: The DRM device pager is based on OBJT_DEVICE, OBJT_MDEVICE or OBJT_SG objects. All these pagers uses fake pages (vm_page_getfake(), vm_page_updatefake()) for mmaping memory used by GPU to user space. On ARM, fake pages aliases are allowed only if they are backed by fictitious pages (i.e. memory on GPU card), not by normal memory pages (CPU memory). The later breaks ARM basic pmap assumption that

paddr == VM_PAGE_TO_PHYS(PHYS_TO_VM_PAGE(paddr))

and I’m unable, nor as ARM pmap coauthor, to find any reasonable solution. I spent weeks of tests on this, but without success.
