Hello,

Following series attempts to improve the loading of livepatches,
specifically by doing the Xen build ID check ahead of processing any of
the sections in the livepatch payload (alternatives, bug frames...).

Thanks, Roger.

Roger Pau Monne (3):
  xen/livepatch: simplify and unify logic in prepare_payload()
  xen/livepatch: do build-id check earlier
  x86/alternatives: relax apply BUGs during runtime
