Thanks for this patch! It solves my problem with kernel 6.12.11
rebooting at start-up on 486 CPUs, which had me puzzled. (tested on
AM486DX2-66 and CX486DX4-100)

Is there a reason why the patch wasn't accepted? I've proposed using it
for the Tiny Core Linux distro's x86 kernel builds, which target 486DX
and later CPUs.
