Hi Rusty,

After merging the modules tree, today's linux-next build (powerpc ppc64_defconfig)
failed like this:

kernel/params.c: In function 'add_sysfs_param':
kernel/params.c:649:9: error: 'struct module_kobject' has no member named 'kp'
  if ((mk->kp->perm & (S_IWUSR | S_IWGRP | S_IWOTH)) != 0)
         ^

Caused by commit 12491941a26c ("param: do not set store func without write perm").

I have used the modules tree from next-20141217 for today.
