Hrm... git request-pull can't find the commit on the server (it's been quite a while now, maybe some mirroring issue), so didn't put the branch name in properly. The branch name is "merge", ie: git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git merge Cheers Ben. > Basically, some (radeon) adapters have issues with MSI addresses above > 1T (only support 40-bits).

Hi Linus ! This series fix a nasty issue with radeon adapters on powerpc servers, it's all CC'ed stable and has the relevant maintainers ack's/reviews. Basically, some (radeon) adapters have issues with MSI addresses above 1T (only support 40-bits). We had powerpc specific quirk but it only listed a specific revision of an adapter that we shipped with our machines and didn't properly handle the audio function which some distros enable nowadays. So we made the quirk generic and fixed both the graphic and audio drivers properly to use it. Without that, ppc64 server machines will crash at boot with a radeon adapter. Note: This has been brewing for a while, it just needed a last respin which got delayed due to us moving ozlabs to a new location in town and other such things taking priority. Cheers, Ben.
