Hmm. The patch there looks better than any alternative I can think of.
It uses the same spinlock name for the whole array, but I think it's
only used for lockdep printouts, so that should be fine.

Send me the patch with signed-off and tested-by, and perhaps have a
few more people test it. The powerpc and sparc people both use it in
their 32-bit versions and have responsible maintainers, so it might be
worth it double-checking with BenH and DaveM about it, just in case.
Added to the Cc.
