I pushed a branch on my arm git: git://linux-arm.org/linux-2.6-lp.git pci-host-generic I can also resend the patches, whatever it is best for you.

Sometimes > it works well enough, although more often than not tabs get lost. I just tried applying the patches locally here. The patch looks the same way for me, but 'git am' actually works while 'patch' does not. Maybe Bjorn is using an outdated git version. While the patch clearly shouldn't have been sent that way, I think git has been changed now to work around that. I'm using a git-2.1 snapshot here.

In my mind, posting patches to the list is implicitly a request for comments, so I usually don't pay too much attention to things explicitly marked "RFC" because I figure that's a hint that "this is work-in-progress, please comment if you see anything obviously broken."

I decided to give it an RFC tag because it is a rework of existing code on top of the new range parsing API and also new iospace remap API, I just wanted to be cautious.

The number of windows allocated for the host bridge depends on the bus resource. Instead of first allocating the windows and then limit the bus resource, this patch reshuffles the code so that if any limitation is applied to the bus resource it is taken into account in the windows allocation.
