Ah, good point...
My intent was to merge as soon as https://lkml.org/lkml/2012/12/5/201 was responded to. The question should not have blocked merging, so I should have followed up, but the again, so should have you. ;-)
I queued the patches, and if testing goes well, will push them to -tip in a few days.
The remaining issue for invoking srcu_read_lock() from offline CPUs is that lockdep does tracing that uses RCU. So your patch 4/8 is incomplete, though a good step towards allowing SRCU to be invoked from offline CPUs. Thoughts on getting the rest of the way there?
Thanx, Paul
