    Subject[PATCH 4.14 137/165] x86/irqflags: Mark native_restore_fl extern inline
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Nick Desaulniers <ndesaulniers@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")
