Say Y here to enable the debug mode for the non-VHE KVM EL2 object.
Failure reports will BUG() in the hypervisor. This is intended for
local EL2 hypervisor development.
If unsure, say N.

help
Say Y here if you want to show the stage-2 kernel pagetables

who are working in architecture specific areas of the kernel.
It is probably not a good idea to enable this feature in a production
kernel.
