Gdb does not know about kernel internals and we shall have to write page table walker etc. Crash is already doing all this stuff. It also uses gdb as backend to retrieve important debugging info etc. So why to duplicate the effort and enable gdb to know about kernel internals and implement page table walker etc. Anyway, a user space utility knowing about kernel internals is bad because kernel changes so fast and keeping pace with it becomes an maintenance nightmare. On the side note, this year at OLS, maneesh conducted a BOF on sort of creating a library in kernel like klibc which is maintained with kernel and user space analysis tools can take advantage of that libarary and get some reprieve in terms of maintenace overheads.
