is also map -> RX -> unmap, but real RX model in a NIC could be more
complicated considering packets can come spontaneously and many drivers
are using pre-mapped buffers pool. This is in the TBD list.

otherwise, if users use old version to run on newer kernel, the random
expansion value will cause side effect on newer kernel.

-> transmission -> unmap. Transmission delay
reduces the contention of IOMMU. Here a delay is added to simulate
the transmission for TX case so that the tested result could be
more accurate.
RX case would be much more tricky. It is not supported yet.

sched_group
isn't a subset of sched_domain. So they can result in picking an idle cpu

disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable because of requesting.

Right now, irq core supports requesting irq with IRQF_NO_AUTOEN, this means
the driver doesn't need to call irq_set_status_flags any more.

This patchset added IRQF_NO_AUTOEN for request_irq() and converted
drivers/input to this new API.
Other drivers will be handled afterwards.
