From: Nick Desaulniers <ndesaulni...@google.com>
commit 1f59a4581b5ecfe9b4f049a7a2cf904d8352842d upstream.
This should have been marked extern inline in order to pick up the out
of line definition in arch/x86/kernel/irqflags.S.
Fixes: 208cbb325589 ("x86/irqflags: Provide a declaration for native_save_fl")
