I love the fact that you're doing so much cleanup. Thanks for all the work in this! Obviously all this code is quite sensitive, so I put it on pci/resource to get more exposure in -next. If it turns out that we trip over things or just don't feel comfortable yet for v6.18, we can always defer this part until the next cycle. I will also watch for acks from the m68k, mips, and sparc maintainers for those pieces. Bjorn
