Revert then solve the bloat another way. I think we can move it to a > seperate module and only load it during pci_probe.

Then in i915_init(), after calling pci_register_driver(), iterate over pciidlist[] and call pci_add_dynid() for each entry. Finally, call pci_free_dynids(). The problem is that after manually unbinding the driver via sysfs, you can't bind it again. Also, as soon as Intel introduces a discrete GPU (e.g. in a dock, hotplugged via Thunderbolt), the whole idea falls apart. How many bytes are we talking about here anyway? I imagine it's less than a page. Honestly I think it's not worth the effort. I'm wondering why noone else is seeing this crash, myself included. Is the driver somehow unbound and rebound on Chris Murphy's machine? @Chris Murphy: You may have noticed an 8 second delay on reboot with 4.15. Before you waste time bisecting it: A fix is already queued for 4.16 and marked for stable: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?id=493fb50e958c Have a pleasant fin de weekend.
