It is recommended that you build a soft-float userspace instead.

- depends on PPC64
- default y
- help
- Cause IO segments sent to a device for DMA to be merged virtually
- by the IOMMU when they happen to have been allocated contiguously.
- This doesn't add pressure to the IOMMU allocator. However, some
- drivers don't support getting large merged segments coming back
- from *_map_sg().
-
- Most drivers don't have this problem; it is safe to say Y here.

+config SPARSE_IRQ
+ bool "Support sparse irq numbering"
+ default y
+ help
+ This enables support for sparse irqs. This is useful for distro
+ kernels that want to define a high CONFIG_NR_CPUS value but still
+ want to have low kernel memory footprint on smaller machines.
+
+ ( Sparse IRQs can also be beneficial on NUMA boxes, as they spread
+ out the irq_desc[] array in a more NUMA-friendly way. )
+
+ If you don't know what to do here, say Y.
