[PATCH 2/2] xen: Kconfig: nest Xen guest options

From: Jason Andryuk
Date: Wed Oct 14 2020 - 13:54:03 EST


Moving XEN_512GB allows it to nest under XEN_PV. That also allows
XEN_PVH to nest under XEN as a sibling to XEN_PV and XEN_PVHVM giving:

[*] Xen guest support
[*] Xen PV guest support
[*] Limit Xen pv-domain memory to 512GB
[*] Xen PV Dom0 support
[*] Xen PVHVM guest support
[*] Xen PVH guest support
