module cleanup (0/5)

[Roman Zippel]

Hi,

I will shortly send a few patches that cleanup the module code a bit.
All patches are independent. Please apply.

1. Replace get_mod_name/put_mod_name with getname/putname.
2. Make the various query functions more compact, by removing the second
   loop to calculate the required space and integrating it into the main
   loop.
3. Remove __MODULE_STRING() in favour of __stringify().
4. Introduce two macros mod_for_each_locked/mod_for_done_locked to safely
   iterate over the module list.
5. Remove obsolete get_kernel_syms system call.

The first 3 changes are trivial.
Patch 4 unifies all the code which loops over the module from an exception
context, so all that code now does correct locking.
get_kernel_syms is not used by modutils anymore. AFAIK get_kernel_syms is
only used by klogd and works fine without it.

bye, Roman
