Isn't this only a notification (warning if you will), not an error?;a=blob;f=arch/x86/Kconfig;h=a6efe0a2e9ae613a81bedec5e4772698d16541cc;hb=HEAD#l1410
"This feature requires gcc version 4.2 or above, or a distribution gcc
with the feature backported. Older versions are automatically detected
and for those versions, this configuration option is ignored. (and a
warning is printed during bootup)"

Actual error messages start at:

Hard to tell from here where the cause is. Cc'd Jeremy as somebody who
knows paravirt.h. Thread start:
