Oops, I had intended to do so. Apparently I forgot to set the subject line of the cover letter too. :-( I don't want to irritate folks with an immediate repost of the whole series, but I'm cc'ing the linux-arm-kernel list on this email. I'll repost a v3 and include linux-arm-kernel before I ask Stephen to pull this stuff into linux-next. For anyone who is doing irq_domain work, please be aware of these patches that are probably going to be merged for v3.4. You'll need to coordinate with me before your patches hit linux-next, otherwise you will have a build failure. The patches can be found here: http://thread.gmane.org/gmane.linux.kernel/1242692 g. > > I tested what you had as of this morning and it works fine for me.
