[PATCH v2 0/6] powerpc: queued spinlocks and rwlocks
v2 is updated to account for feedback from Will, Peter, and
Waiman (thank you), and trims off a couple of RFC and unrelated
patches.
Thanks,

[PATCH 0/8] powerpc: queued spinlocks and rwlocks
This series adds an option to use queued spinlocks for powerpc, and
makes it the default for the Book3S-64 subarch.
This effort starts with the generic code so it's very simple but
still very performant. There are optimisations that can be made to
slowpaths, but I think it's better to attack those incrementally
if/when we find things, and try to add the improvements to generic
code as

[PATCH v4 0/6] powerpc: queued spinlocks and rwlocks
Updated with everybody's feedback (thanks all), and more performance
results.
What I've found is I might have been measuring the worst load point for
the paravirt case, and by looking at a range of loads it's clear that
queued spinlocks are overall better even on PV, doubly so when you look
at the generally much improved worst case latencies.
I have defaulted it to N even though
