When you are in kenerl mode, you can use the copy_to_user() function to 
put some kernel data in a user buffer.
So you will have to write a system call (to enter in kernel mode) and to 
copy the the needed kernel data in a user buffer. But check all the 
system calls before. Maybe there is one which fits your needs.
