The mips reloc patch introduced new allocations which were done before
add_unformed_module but never freed them in case of an error. A new hook in
Linux 3.19 called module_arch_freeing_init can be used for freeing memory
which were allocated during this init phase.
The problem can be seen when trying to load a module (via busybox insmod)
when it was already loaded.
free -m
for i in `seq 1 100`; do
/sbin/insmod /lib/modules/*/ath9k.ko >& /dev/null
done
free -m
This simple loop would leak ~3.2 MB.

It currently does not seem to make a difference anymore, except by
increasing compressed kernel image size
