Subject: [PATCH 0/4][RFC] Lockdep enablement for seqcount/seqlocks

I wanted to send this out again for feedback.

This patch series enables lockdep for seqcount/seqlock structures,
as well as provides the required cleanups to explicitly initialize
the seqcount structures on u64_stat_sync users.

In addition the last two patches in this provide naive fixes to
some of the issues the new lockdep infrastructure caught.

I'd greatly appreciate any thoughts or feedback on the series!

thanks
-john
