EARLY_AP_STARTUP was introduced in 2016 (commit fdce57a042) with note:
As a transition aid, the new behavior is moved under a new
kernel option (EARLY_AP_STARTUP). This will allow the option
to be turned off if need be during initial testing. I hope to
enable this on x86 by default in a followup commit ...
It was enabled by default, but became effectively mandatory (on x86)
some time later. Move it to DEFAULTS to avoid an unbootable system if
the option is left out of a custom kernel configuration file.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
