SubjectINFO: trying to register non-static key.
Hi,

after upgrading from 3.8.0-rc7 to 3.9.0-rc1, the following message appears
after booting and after dm-crypt (LUKS) partitions are mounted and
exported via NFS:

-------------------------------

the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

This has been reported in January[0] and a bad commit has been singled
out:

> commit ec8acf20afb8534ed511f6613dd2226b9e301010

However, git-revert'ing this commit did not help in my case (powerpc32,
uni processor). Please find full dmesg & .config here:

Thanks,
Christian.
