BTW, it would have helped to note that said commit is currently
available only via the tip tree.
With that IMO this patch should go in via the tip tree, too.

I suspect some or all all of the other three options should be
dropped as well, given that 32-bit XEN_PV guests are already
unsupported as of
commit a13f2ef168cb2a033a284eb841bcc481ffbc90cf

x86/xen: remove 32-bit Xen PV guest support
Xen is requiring 64-bit machines today and since Xen 4.14 it can be
built without 32-bit PV guest support. There is no need to carry the
burden of 32-bit PV guest support in the kernel any longer, as new
guests can be either HVM or PVH, or they can use a 64 bit kernel.
Remove the 32-bit Xen PV support from the kernel.
and 32-bit Pentium4 and Atom CPUs don't run modern Xen hosts.
Most likely this should be
depends on X86_64 || (X86_32 && X86_PAE && X86_GENERIC)
to say that running 32-bit XEN_PVHVM guests is still supported
allowed on 64-bit hosts, but not on pure 32-bit machines.
