Updating env/kernel-config after rebasing/kernel version bump

[Philip Prindeville]

Hi,

I originally set up my env/kernel-config a long time ago (like 2018) by hand, and since then the kernel has gone through several bumps.  How do I easily refresh it to pick up new stuff from target/linux/x86/64/config-${KVER} (where KVER=5.15 currently)?  Is there a handy script or make target to do this?

Thanks,

-Philip
