Very nice series, I applied it right away with the exception of this patch. I don't like naming it "highmem" because normally this describes a hardware feature, namely a technique for reaching memory that is outside the CPUs address space. What we have here is a technique for reaching memory that is outside the range of a poorly chosen variable type ;) That said my alternative suggestions are not very striking and range from /dev/mem1 to /dev/uppermem or /dev/mem-upper. Any other ideas?
