Subject: [PATCH 0/3] Module load failure race fix.

Hi all,

	This bug has been around since 2009, but only reported now.
I'm debating whether to cc: stable.

To fix it, I had to change module_free.  Please ensure I haven't broken
your arch!

Thanks,
Rusty.

Rusty Russell (3):
  module_arch_freeing_init(): new hook for archs before
    module->module_init freed.
  module: remove mod arg from module_free, rename module_memfree().
  module: fix race in kallsyms resolution during module load success.
