You of course still have the option to simply delete anything that is not yet immutable, or remove the irq_chip patching support. The kernel has been screaming for three years now, and these drivers are pretty much unmaintained. My bet is that nobody will notice, and I suspect tglx will gladly take patches deleting unmaintained code. Once that's done, you can drop the immutable flag, which won't serve any purpose anymore. M. --=20 Without deviation from the norm, progress is not possible.
