Please find here patches for XEN_MAX_DOMAIN_MEMORY:
[PATCH 1/2] xen: Fix XEN_MAX_DOMAIN_MEMORY to be selectable
[PATCH 2/2] xen: Make XEN_MAX_DOMAIN_MEMORY have more sensible
defaults for 32-bit builds
What's the rationale?

The first patch is actually bug fix. You can not define just "int"
without description in Kconfig. As the result this option will not be
visible in menuconfig. Even if you will change it in .config make
oldconfig will set it up for default value. So you need to add any
description to it as all others int options have.
No, that was deliberate, because I don't really think there's a need to
change it.
Second patch is more optional and it's just suggestion to use for 32
bit more corresponding value.
While it would be very silly to put 128GB of actual RAM on a 32-bit
machine, systems can have non-contiguous RAM placed at high addresses,
which would no longer be accessible.
