A new kgdb feature will soon land (kgdb_earlycon) that lets us run

important that the break hook is setup by the time we process
"kgdbwait".

Right now the break hook is setup in debug_traps_init() and that's
called from arch_initcall().  That's a bit too late since
kgdb_earlycon really needs things to be setup by the time the system
calls dbg_late_init().

Applied to arm64 (for-next/misc), thanks!
