[RFC 01/13] x86/paravirt: Turn KASAN off for parvirt.o
From: Andy Lutomirski
Date: Fri Jan 08 2016 - 18:15:44 EST
Otherwise terrible things happen if some of the callbacks end up
calling into KASAN in unexpected places.
This has no obvious symptoms yet, but adding a memory reference to
native_flush_tlb_global without this blows up on KASAN kernels.
