This patch adds CONFIG_SYSTEM_SUSPEND guards around freeze_domains
and thaw_domains functions.
This ensures they are only compiled into the hypervisor when the system
suspend functionality is enabled, aligning their inclusion with their
specific use case.

We already have a generic check to confirm 32-bit domain are not using

Just curious: How does x86 come into play here? Xen inherited this un-
written rule

Hi Ayan, Stefano,
This doc looks nice overall!
However I do think that maybe the role part should be separate from all

Thanks!

Yann
