Updating the kernel configuration fragments to fix the following
issues:

  - remove options that are no longer in the 3.4 kernel
  - disable unused, but large kernel modules
  - fix kconfig audit warnings for x86 BSPs
  - make uprobes reusable by multiple fragments

The following meta branch commits are represented by this update:

  3da1172 uprobes: split into enable and patch fragments
  17ec51a meta: cleanup invalid/obselete 3.4 CONFIG options
  b5cee42 meta: disable OCFS2 by default
  efe937e meta: drm: tag DRM options as 'hardware'

linux-yocto-tiny: Add tiny recipe for the 3.4 linux-yocto kernel

This recipe builds the "tiny" kernel type defined by the linux-yocto
meta-data. Support is defined for the qemux86 machine via
common-pc-tiny.scc in the linux-yocto meta branch. The resulting
kernel is 1.8 MB and boots to a serial console with with qemux86 and
core-image-minimal using the following command:

qemu -kernel tmp/deploy/images/bzImage-qemux86.bin -initrd tmp/deploy/images/core-image-minimal-qemux86.cpio.gz -append "root=/dev/ram0 console=ttyS0" -nographic

qemu: When applying qemu-mips workaround, check the file exists first

If qemu-mips was disabled as done in some distros, this wrapper would fail.
Therefore check if the file exists before wrapping it.

linux-yocto-bsps: update hardware reference BSPs to v3.4.11

The hardware reference BSPs are missing the update to 3.4.11
that the qemu* machines received several weeks ago.

Bumping to 3.4.11 specifically addresses the segfaults being
seen with rpm on the beagleboard.
