I have saved following patch from Arnd for ages.
First I was worried about the use of weak - but we do that in other
places. And then I just forgot it until now.
Should be easy to adopt to current kernel - but too late for me today.

We could in theory create a new EXPORT_SYMBOL variant that does not
reference the symbol directly. This does a little less compile-time
checks but helps reduce the noise. The big advantage of this
would be that we could once again build kernels with -Werror on
developer machines.

pm_unregister_all is removed in the -mm tree, from a patch in my tree.
