Well, the base problem is that virt_to_*/*_to_virt were only ever intended to work on addresses mapped to system RAM. See Documentation/IO-mapping.txt. Why not just store argument one to ioremap to calculate the physical addresses you are working with in virtual space? -- Matt Porter mmporter at home.com This is Linux Country.
