help
This option will show the mapping relationship between hardware irq
numbers and Linux irq numbers. The mapping is exposed via debugfs
in the file "irq_domain_mapping".
If you don't know what this means you don't need it.

bool "Support sparse irq numbering" if MAY_HAVE_SPARSE_IRQ
---help---
Sparse irq numbering 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 interrupt descriptors in a more NUMA-friendly way. )
If you don't know what to do here, say N.

Merge tag 'sti-dt-for-v4.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pchotard/sti into fixes
STi DT fix:
Since v4.10-rc1, xhci is complaining in loop with :
[ 801.953836] usb usb6-port1: Cannot enable. Maybe the USB cable is bad?
[ 801.960455] xhci-hcd xhci-hcd.0.auto: Cannot set link state.
[ 801.966611] usb usb6-port1: cannot disable (err = -32)
set property "snps,dis_u3_susphy_quirk" in DT fix it.
