[PATCH v2 0/4] Fix queued spinlocks and a bit more

[Nicholas Piggin]

This didn't seem to send properly, apologies if you get a duplicate.

Patch 1 is the important fix. 2 might fix something, although I haven't
provoked a crash yet.

Patch 3 is a small cleanup, and patch 4 I think is the right thing to do
but these could wait for later.

Since v1:
- Improved comments, changelogs, code style / wrapping.

Thanks,
Nick
