[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

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
