mips: Free memory when load_module fails (#14453)
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.
