s!arm!xen/public! in the subject seeing as two thirds of the modifications are in non-ARM headers. Acked-by: Andrew Cooper <andrew.coop...@citrix.com> This wants backporting as a build fix, so should be considered for 4.15 at this point. I wonder why our header checks don't pick this up. Do we need to throw a -pedantic around?
