Merge git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async-for-30

* git://git.kernel.org/pub/scm/linux/kernel/git/arjan/linux-2.6-async-for-30:
  fastboot: remove duplicate unpack_to_rootfs()
  ide/net: flip the order of SATA and network init
  async: remove the temporary (2.6.29) "async is off by default" code

Fix up conflicts in init/initramfs.c manually
