Pull arch/tile updates from Chris Metcalf:
"These changes provide support for PCIe root complex and USB host mode
for tilegx's on-chip I/Os.
In addition, this pull provides the required underpinning for the
on-chip networking support that was pulled into 3.5. The changes have
all been through LKML (with several rounds for PCIe RC) and on
linux-next."
