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.

After the last architecture switched to generic hard irqs the config

for !CONFIG_GENERIC_HARDIRQS can be removed.

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.
