Greg Kroah-Hartman	acc7c954b0	refcount: change EXPORT_SYMBOL markings ... commit d557d1b58b upstream. Now that kref is using the refcount apis, the _GPL markings are getting exported to places that it previously wasn't. Now kref.h is GPLv2 licensed, so any non-GPL code using it better be talking to some lawyers, but changing api markings isn't considered "nice", so let's fix this up.

Ingo Molnar	9dcfe2c75b	locking/refcounts: Change WARN() to WARN_ONCE() ... Linus noticed that the new refcount.h APIs used WARN(), which would turn into a dmesg DoS if it triggers frequently on some buggy driver. So make sure we only warn once. These warnings are never supposed to happen, so it's typically not a problem to lose subsequent warnings.

Peter Zijlstra	29dee3c03a	locking/refcounts: Out-of-line everything ... Linus asked to please make this real C code. And since size then isn't an issue what so ever anymore, remove the debug knob and make all WARN()s unconditional.
