Hey everyone, Here's the second RFC for the irq_domain patches. =A0I could use some help testing now. =A0I still expect there will be a few bugs. =A0The series is based on v3.3-rc1, and I've pushed it out to my git server: git://git.secretlab.ca/git/linux-2.6.git irqdomain/nextCan you post to linux-arm-kernel too so people are aware of this work and stop posting dead-end irqdomain patches.
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. Looks like the only diff is the VExpress code. I'm working on rebasing my domain support for generic irqchip now. Robquoted

of the generic irq_domain infrastructure. I'm taking a different approach that I originally intended. Originally I intended to start with the basic design of irq_host from powerpc, but there were some things about the implementation that I didn't like, so I was going to reimplement those bits and then migrate powerpc over to use it. =A0That was a mistake and would have resulted i=

a lot more work. =A0Instead, I should have started with the powerpc irq_host code, moved it to a common location, and then reworked it in place. =A0The powerpc code is working and well tested. =A0It is a lot l=
