Ok, clearly Andy didn't get the 32-bit SMP bringup path right.
Presumable tested a 32-bit UP image, or in a single-cpu VM?

Andy?

The warning only triggers on 32-bit SMP.  The issue seems to be that boot_cpu_has(X86_FEATURE_PCID) is true despite setup_clear_cpu_cap.  I'm still trying to figure out why.  I'll hopefully have a patch after lunch.

Nah, that was a false alarm although there's arguably a real bug here.
But I found the issue causing the warning.

x86's boot code is so inconsistent and weird that I'm a bit surprised
that it works at all sometimes.
