Cover letter [PATCH 0/7] smp/hotplug rework / lockdep annotate
These here patches rework the cpu hotplug state machine and add two lockdep (crossrelease) annotations.
The rework is quite invasive, but was suggested by Thomas as being the right way to go about doing things :-)
These patches have been tested with Steve's hotplug stress script, as well as two new hotplug test scripts which test cpu up/down rollback through explicit failure injection (see last patch).
Where cpu-down used to insta-trigger a lockdep splat, I am no longer able to trigger anything with these patches applied.
