Hello all,
I'm porting uClinux on the Cortus APS3 processor and in order to write specifically the setup_arch function I need to understand correctly the structure mm_struct, but I have some doubts. Could someone please explain to me the purpose of the following variables :

(uClinux/uClinux-dist/linux-2.6.x/include/linux/sched.h)

   total_vm
   locked_vm
   shared_vm
   exec_vm
   stack_vm
   reserved_vm
   def_flags
   nr_ptes
   start_brk
   brk
   start_stack
   arg_start
   arg_end
   env_start
   env_end

I haven't find interesting documentation about this so if someone has an idea it will be greatly apreciated.
Thanks in advance.
Stéphane Lambert
