The PPC code just accesses physical memory, as is. > I suggested another solution: > http://patchwork.ozlabs.org/patch/123074/ > > This has the disadvantage, as discussed in the thread, that the address > passed to mmap is not guaranteed to be returned. I don't see why this would be needed. I think you got things backwards. Please note that I do NOT complain that "md 0x100" or "md 0" segfaults in general; it is IMO perfectoy OK to do this if there is no memory. But the "bdinfo" command reported that memory starts at 0, and then both these commands are supposed to work. I am not asking for any specific mapping - I just ask for _consistent_ information provided to the user.
