Some of x86 bare-metal and Xen CPU initialization code is common between the two
and therefore can be factored out to avoid code duplication.

As a side effect, doing so will also extend the fix provided by commit
a7fcf28d431e ("x86/asm/entry: Replace this_cpu_sp0() with current_top_of_stack()
to x86_32") to 32-bit Xen PV guests.

This does not apply to the latest x86 tree (tip:master).

Thanks,

Yes, I was somewhat out-of-date, sorry. Let me re-test this and submit v2.
