Btw., that the heck is going on with the commit that introduced the build failure: commit bd9ddc875b6659f9f74dcfd285c472bc58041abd Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@...rix.com> AuthorDate: Mon Jun 20 17:52:13 2011 -0700 Commit: Jeremy Fitzhardinge <jeremy.fitzhardinge@...rix.com> CommitDate: Mon Jul 18 15:43:46 2011 -0700 It was apparently rebased shortly before the merge window and sent to Linus 3 days later, with little to no linux-next testing ... I'm absolutely unhappy about how the Xen tree is being run. It's using a sloppy, crappy workflow and it is producing crap.
