Hans Petter Selasky c7818b48b6 - Update the OFED Linux Emulation layer as a preparation for a
hardware driver update from Mellanox Technologies.
- Remove empty files from the OFED Linux Emulation layer.
- Fix compile warnings related to printf() and the "%lld" and "%llx"
format specifiers.
- Add some missing 2-clause BSD copyrights.
- Add "Mellanox Technologies, Ltd." to list of copyright holders.
- Add some new compatibility files.
- Fix order of uninit in the mlx4ib module to avoid crash at unload
using the new module_exit_order() function.
