FYI, a commit in this tree broke today's -tip build on x86:

 drivers/built-in.o: In function `pci_dev_reset':
 pci.c:(.text+0x95ed): undefined reference to `pci_dev_reset_methods'
 pci.c:(.text+0x95fd): undefined reference to `pci_dev_reset_methods'

I wont have time to bisect it today but wanted to give you a heads up.
 
( About 20% failure rate in randconfigs, so it will be reported by others too 
  i suspect. I suspect looking at the symbol names and the Kconfig rules 
  around them the bug should be apparent. Or if not then the relevant Kconfig 
  rules are, by definition, too complex ;-)
