The right way to handle header updates is to split the linux-header updates into a "dummy" update (that just adds the header) and replace that patch with a proper header update once the changes hit Linux mainline. I have not looked at the contents of the series otherwise -- but if this is a system header (and not something that defines the kernel<->vmm interface), how do you make sure that your system has that installed? Maybe I'm misunderstanding.
