Pull xen fix from Juergen Gross:
"One fix for a regression when booting as a Xen guest on ARM64
introduced probably during the 5.9 cycle. It is very low risk as it is
modifying Xen specific code only.
The exact commit introducing the bug hasn't been identified yet, but
everything was fine in 5.8 and only in 5.9 some configurations started
to fail"
