Hello, I was auditing get_user_pages() users and I've noticed that omap_vout_uservirt_to_phys() is apparently called for arbitrary address passed from userspace. If this address is in VM_IO vma, we use vma->vm_pgoff for mapping the virtual address to a physical address. However I don't think this is a generally valid computation for arbitrary VM_IO vma. So do we expect vma to come from a particular source where this is true? If yes, where do we expect vma comes from? Thanks for clarification.
