Hm. Those are false alarms. I guess I could do something to hide them, but
there's nothing inherently wrong with correctly used abs symbols. Is there
someway to whitelist them?
Yes. Just add them to arch/i386/boot/compressed/relocs.c safe_abs_syms.
OK, how's this?
Subject: xen: suppress abs symbol warnings for unused reloc pointers
The Xen code generates some abs symbols which are OK from a relocation
perspective.
