49 Say Y here to enable the debug mode for the non-VHE KVM EL2 object.

60 Say Y here to enable pKVM hypervisor stacktraces on hyp_panic()
62 If using protected nVHE mode, but cannot afford the associated
63 memory cost (less than 0.75 page per CPU) of pKVM stacktraces,
66 If unsure, or not using protected nVHE (pKVM), say N.
