There's no reliable way to get the old microcode revision which was

The primary requirement here is that we report the version of the
microcode
in use at the time of a crash. Keeping history of all updates seems to
me to
beyond the scope of the kernel's responsibilities.
It's not like these updates appear out of the ether. You have to go out
and
grab a new package and install it. User land can keep track of this
much
more easily than the kernel.
I don't mind doing the right thing at all. It is just to inform you that
it was found to be useful.

Thanks ☺.
