(1) Fix request_key() so that it doesn't cache a looked up key on the current thread if that thread is a kernel thread. The cache is cleared during notify_resume - but that doesn't happen in kernel threads. This is causing cifs DNS keys to be un-invalidateable. (2) Fix a wrapper check in verify_pefile() to not round up the length. (3) Change asymmetric_keys code to log errors to make it easier for users to work out why failures occurred.
