Pull trivial module and virtio fixes from Rusty Russell.

Apparently these were meant for 3.10, but came in after the release.

* tag 'modules-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
  modpost.c: Add .text.unlikely to TEXT_SECTIONS

* tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux:
  virtio: remove virtqueue_add_buf().
  lguest: rename i386_head.S
  virtio_blk: Add missing 'static' qualifiers
  virtio: console: Add emergency writeonly register to config space
  virtio_pci: better macro exported in uapi
