I think so. The problem we have now is __pa() macro that we only use
on 32-bit. I'll queue this for overnight tests to make sure and if it
indeed works then 3.19 should be fine.
All tests passed.
I'd still take your patch for 3.19 though because I'm fixing the 32-bit
reloading path properly and will remove the ifdef afterwards.
And even then, I'd like to prevent loading the module on a paravirt
guest if it is totally unneeded there.
I wonder whether we should prevent all guests (not just paravirt) from
loading microcode driver (and from doing early microcode loading).
