The Linux Kernel is Finally Letting Go of i486 CPU Support

The support remained in the Linux kernel all these years after every other major platform dropped it.

It's FOSS
This means that support for true 386s is gone as well, doesn't it?

I maintain both a 64-bit #Linux #distro and a 32-bit version because the latter is nearly as easy as just doing multilibs [which is what #Debian and some other distros do].

But my 32-bit distro won't boot on genuine 386 PCs even now, before kernel 7.1 arrives, will it?
