[openib-general] InfiniPath driver announcement

[Roland Dreier]

I got my system set up again.  I needed the following patch to work
with the latest kernel (which no longer has io_remap_page_range).  I'm
also throwing in a warning cleanup.

I'm still seeing some problems with the SM bringing up the port, which
I'll start debugging now.

BTW, ipath_mmap() probably needs to be rewritten or broken up into
subfunctions -- the fact that the parameters of io_remap_pfn_range()
are squeezed so hard against the right margin indicates that there are
too many levels of { } in the function.

 - R.
