JFYI, if you want to build a v6.2-based kernel, you can use my m68k-v6.2
branch, which includes Al's fix, and all m68k changes queued for
v6.3-rc1.
Alternatively, you'll have to wait for v6.3-rc1 (assumed Al's fixes
will land there, they're still not in linux-next), or until the fixes
have been backported to v6.2-stable. Or just create your own ;-)
