FYI, there's a post-rc1 build regression with certain configs:

 drivers/built-in.o: In function `pci_hp_deregister':
 (.text+0xb166): undefined reference to `pci_hp_remove_module_link'
 drivers/built-in.o: In function `pci_hp_deregister':
 (.text+0xb19f): undefined reference to `pci_destroy_slot'
 drivers/built-in.o: In function `__pci_hp_register':
 (.text+0xb583): undefined reference to `pci_create_slot'
 drivers/built-in.o: In function `__pci_hp_register':
 (.text+0xb5b1): undefined reference to `pci_hp_create_module_link'
 make: *** [.tmp_vmlinux1] Error 1
