Since module_free() is also (ab)used by BPF and trace code, -let's keep it to simple allocations, and provide a hook called before -that. - -This means that avr32, ia64, parisc and s390 no longer need to implement -their own module_free() at all. avr32 doesn't need module_finalize() -either. - -Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> -Cc: Chris Metcalf <cmetcalf@ezchip.com> -Cc: Haavard Skinnemoen <hskinnemoen@gmail.com> -Cc: Hans-Christian Egtvedt <egtvedt@samfundet.no> -Cc: Tony Luck <tony.luck@intel.com> -Cc: Fenghua Yu <fenghua.yu@intel.com> -Cc: "James E.J.
