Support for full DMA access of devices with 32bit memory access only
on systems with more than 3GB. This is usually needed for USB,
making when dealing with multi-core CPU chips at a cost of slightly
increased overhead in some places. If unsure say N here.

+ default n
+ ---help---
+ Select this option to enable fine granularity task irq time
+ accounting. This is done by reading a timestamp on each
+ transitions between softirq and hardirq state, so there can be a
+ small performance impact.
+
+ If in doubt, say N here.
