CC peterz.

I wonder if it's because I converted some static keys to _RO
DEFINE_STATIC_KEY_FALSE_RO(init_on_alloc);.
...
DEFINE_STATIC_KEY_FALSE_RO(init_on_free);

I thought it was ok since we only enable them during init. But maybe it's 
incompatible with use by modules? Not that I immediately see how 
drm_kms_helper(E+) uses them.

Andrew, I'm fine if you drop the patchset for now. I fear the next version would 
be tedious to integrate in form of -fix-fix patches anyway...
