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.
