Subject[PATCH] x86/irqflags: mark native_restore_fl extern inline
From
Fixes commit 208cbb325589 ("x86/irqflags: Provide a declaration for
native_save_fl")

This should have been marked extern inline in order to pick up the out
of line definition in arch/x86/kernel/irqflags.S.

Cc: stable@vger.kernel.org # 4.18, 4.14, 4.9, 4.4
