Linux kernel removing 486 support

The patch does not apply cleanly?
CNK:
@cparke
Firefox or Chromium on a 486 is madness, there's no hope of that. elinks-nodep.tcz is a good web browser option for 486 except it doesn't do HTTPS. links.tcz should work if you have more patience and RAM. Also dillo.tcz and links-full.tcz if you have enough RAM to run X. I'm not sure about netsurf.tcz, and anything based on Firefox or Chrome browser engines (eg. Brave) will have vastly higher system requirements.
@Juanito
The patch applied for me on the latest kernel release, but "patch" wouldn't apply it to arch/x86/kernel/cpu/microcode/amd.c in kernel v6.12.11.
I'm not that good with "patch", there might be options that will make it work. Since the function that's changed is identical I copied the changed lines over manually. It might also be different if you use Git, which I'm even more lost with.
I can look back at it again if you really want, but I just deleted all the kernel building stuff from my VPS to save space last night since I thought nothing more was happening with it!

This patch is only going to help up until they remove the 486 support, from that point forward it’s a much bigger task to maintain if at all.
Hard to say if/when they will do it. It does look like the fix CNK mentioned was just merged into mainline. Perhaps they’ll keep the 486 support in unit after the next long term kernel release.

Right.
i can remember buying my first new PC, after much concideration and i managed to get it to be a 586
at great value and pleasing.
That was in 1996. "Cyrix 5x86 " chip.
so i don't know the exact date i486 was introduced, but maybe 1991 .....?
Perplexity says 1989 ....
so nearly 37 years ago.
i have no doubt that billions of the working machines still exist.
regards

Sure, I wouldn't expect TCL to keep 486 support if they do that.

Great, yes I see it here.
