There are five additional commits that are required to make that driver
actually buildable: the tilegx GXIO IORPC framework, including DMA support,
the GXIO support for the tilegx ethernet engine, <asm/io.h> support for
MMIO-based readb/writeb, and a minor refactoring change.  These have been
through some rounds of review on LKML and have been on linux-next for a
couple of months.

I thought David was queueing the driver for 3.6, and he presumably thought
all the prerequisite core tile changes were already in 3.5 :-)

I'm happy to just say "oh well" and leave the tilegx network driver
unbuildable until 3.6.  Or, you can pull those five commits; they are 100%
tile-specific and only affect tilegx iorpc drivers, of which this is now
the only one in the tree.  (Two more are queued up in linux-next for 3.6,
namely PCIe root complex and USB host.)
