Description:
linux kernel 4.19.8 can't be loaded on xen 4.11 as dom0. The same isssue is on linux-zen. So all Xen users are affected.

There is a patch for linux but it is not in main stream yet.
Can be the patch, that is integrated to the debian 4.19.9, be commited to the archlinux until patch is in the mainstream.

Additional info:
* package version(s) - linux-4.19.8, linux-zen-4.19.8, aur/xen-4.11
* config and/or log files etc.


Steps to reproduce:
Install xen-4.11 from AUR, configure Xen to use existed archlinux as dom0.
