Yeah, I wasn't sure about that. The logic is that if BIOS has enabled
SME and thus reduction is in place, we need to update x86_phys_bits on
32-bit regardless, right?
But, come to think of it, that reduction won't have any effect since we
have 32-bit addresses and the reduction is above 32-bits, right? And
thus it is moot.
Or?
