hi, this sounds awkward, but how do we allocate mmap to a process, if we want to explicitly do it? used the kmem_cache_alloc(mm_cachep,...) to allocate memory to (task_struct)->mm, later allocated some vm_areas (no dynamic libraries) similarly... after using pgd_alloc to allocate the pgd, added mm to the mmlist and copied all other variables directly from the original mm of that process... then, i tried to start the process... the response was that the system rebooted instantaneously (i expected it to generate some page-faults, but surprisingly nothing like that happened...). On trying to learn about that further, thought i was missing on the PMDs and the PTEs. could someone enlighten me on what could have gone wrong in the above setup. Thanks for your ideas.
