Jurgen, what do you want to do with updating 4.19? Don't we need to
fork a 4.19 branch to avoid the CONFIG_XC change ?
Yes, I think this is the way to go.
Ok. https://xenbits.xen.org/gitweb/?p=mini-os.git;a=summary
master has this fix, and there's a new branch, xen-stable-4.19, starting
from the xen-RELEASE-4.19.0 tag with this change backported.
Xen 4.18 and earlier don't have the symbol restrictions.
You want a related patch on the Xen 4.19 branch to update the Mini-OS
commit in Config.mk.
Juergen
