Sure - we can reasonably rebase portions of that stack of commits:

 earth4:~/tip> gll linus..core/rcu
 7256cf0: rcu: Add diagnostic check for a possible CPU-hotplug race
 04b0625: rcu: Fix RCU & CPU hotplug hang
 7fe616c: rcu: Simplify RCU CPU-hotplug notification
 240ebbf: rcu: Add synchronize_sched_expedited() rcutorture doc + updates
 0acc512: rcu: Add synchronize_sched_expedited() torture tests
 03b042b: rcu: Add synchronize_sched_expedited() primitive
 c17ef45: rcu: Remove Classic RCU

Please mention the magic words "please reset core/rcu to 240ebbf 
before applying these patches" in the mail to me, should i forget in 
the days to come.

(hm, what was i supposed to not forget? Weird.)
