Fwd: Bug#1043437: linux: report microcode upgrade *from* version as well

Hi,

would you mind backporting that patch to stables (at least 5.10
and 6.1 are relevant for Debian)?

Thanks in advance!

I have this in dmesg:

[    0.000000] microcode: microcode updated early to revision 0xa4, date = 2010-10-02

It would be very nice if this message also showed the revision *from*
which it was upgraded, so that info is available without going through
extra hoops to boot without �code upgrade.

This is fixed upstream in a9a5cac225b0 ("x86/microcode/intel: Print
old and new revision during early boot") in 6.3-rc1, but not sure it
will have changes to get backported to stable series upstream.

Would you mind trying to get that applied in the needed stable series?

Regards,
Salvatore

Can you provide a working version of the commit?  As-is, it does not
apply cleanly, so obviously has never even been tested on those kernel
trees.

thanks,

Ouch. Sorry, nowhere even near the resources for that rn :/
