This patch isn't correct.  Quoting from its review:

ivshmem.o should only be linked when CONFIG_EVENTFD is set.  pci.mak has

    CONFIG_IVSHMEM=$(CONFIG_EVENTFD)

The compile error shown above indicates CONFIG_EVENTFD=y for make (since
ivshmem.o gets linked), but !defined(CONFIG_EVENTFD) for C (or else
event_notifier_init_fd() would exist).  Your build tree is messed up, or
the makefiles are broken.  Try starting over with a fresh build tree.

End quote.

[T. Huth]

According to the discussion for the patch that you've mentioned, the
problem should go away after a "make distclean". Can you still reproduce
it after doing a fresh build?
