What am I missing? Thanks, Rajat
Sorry & thanks every one ... I missed out that the kernel is actually executing on the behalf of a user process only, and is hence sharing its virtual address space with a user process all the time. My doubts are clarified. However, what is meant when we that the 1 GB of physical memory is "identity mapped" to 1 GB kernel virtual address space? I think it means that all the user processes have have the 3GB->4GB virtual addresses mapped to the kernel code & data. Is this right?
