tristate "Intel PCIe HCA support"
IB/qib: Begin to use rdmavt for verbs This patch begins to make use of rdmavt by registering with it and providing access to the header files. This is just the beginning of rdmavt support in qib. Most functionality is still being done in the driver, set flags so that rdmavt will let qib continue to handle mr, qp, and cq init.

IB/qib: Add DCA support This patch adds DCA cache warming for systems that support DCA. The code uses cpu affinity notification to react to an affinity change from a user mode program like irqbalance and (re-)program the chip accordingly. This notification avoids reading the current cpu on every interrupt.
