These are the init-dom0less and dom0less xenstore evtchn changes split
from 
https://lore.kernel.org/xen-devel/20250716211504.291104-1-jason.andryuk@xxxxxxx/

The xenstored changes have already gone in.

init-dom0less needs to be changed to handle auto-introduced domains,
which this series does.  Once that is done, dom0less code can populate
the event channel in the xenstore page (which triggers the
auto-population).  The previous posting's ordering of "xen/dom0less:
store xenstore event channel in page" before init-dom0less changes would
have been broken.

Jason Andryuk (8):
  tools/init-dom0less: Make handles global
  tools/init-dom0less: Factor out xenstore setup
  tools/init-dom0less: Only introduce un-introduced domains
  tools/init-dom0less: Switch domain_exists to check xenstore name
  tools/init-dom0less: Use introduced to determine no-enhanced
  tools/init-dom0less: Remove use of err()
  tools/init-dom0less: Continue on error
  xen/dom0less: store xenstore event channel in page
