hwloc (1.8-1ubuntu1.1) is now waiting for approval in trusty-proposed

** Description changed:

+ SRU request:
+ 
+ Please accept hwloc into trusty-proposed.
+ 
+ [Rationale]
+ The libhwloc-plugins package need to depend on ocl-icd-libopencl1 (>= 1.0) | libopencl1 rather than just on libopencl1, since the nvidia driver provides libopencl1 too now.
+ 
+ [Impact]
+ Without a rebuild, the libhwloc-plugins package will pull in the nvidia driver and a massive amount of packages which are not needed (or even recommended). ocl-icd-libopencl1 is the only recommended loader, as NVIDIA's only work with the nvidia driver.
+ 
+ [Test Case]
+ After installing the update, users should be able to install libhwloc-plugins without having nvidia-331 installed as a dependency
+ 
+ [Regression Potential]
+ Low. This is a mere no change rebuild. We only need to make sure that all the newly generated dependencies do not affect the system.
+ 
+

+ ----------------------------

  There appears to be a package dependency cascade that occurred approx 12
  hours ago.  Attempting to install libboost-all-dev causes this:  "0
  upgraded, 791 newly installed, 0 to remove and 3 not upgraded."
  
  The 791 packages include much of the gnome and kde desktops, a web
  browser, some chat clients, all of X11 .. which is crazy for a package
  needed to compile C++ programs for a server.
  
  I traced the dependencies: its a rather long, boring chain ... it
  depends on stuff which depends on  libboost-mpi1.54.0  which causes 694
  packages to be installed
  
  Tracing through eventually leads to  libhwloc5 which seems like it
  should be harmless ..  but that leads to libopencl1  which is a virtual
  package.  If you recall, opencl is a GPU general-purpose-computing
  thing, so, unsurprisingly, we see a dependence on nvidia:
  
  Package libopencl1 is a virtual package provided by:

  Next: apt-get  install nvidia-libopencl1-331-updates  results in: 0
  upgraded, 681 newly installed, 0 to remove and 3 not upgraded.
  
- Tracing through that, we get to  nvidia-331-updates  which requires nvidia-prime which causes this:
