Subjectnative_save_fl() causes a warning
Hi Nick,

It seems that this linux kernel commit of yours:

commit d0a8d9378d16eb3c69bd8e6d23779fbdbee3a8c7
Author: Nick Desaulniers
Date: Thu Jun 21 09:23:24 2018 -0700

x86/paravirt: Make native_save_fl() extern inline

introduced a new warning (with W=1):

./arch/x86/include/asm/irqflags.h:16:29: warning: no previous prototype for ‘native_save_fl’ [-Wmissing-prototypes]
extern inline unsigned long native_save_fl(void)

Please fix it.

Secondly, I am quite curious why you changed only native_save_fl() from
static inline to extern inline, when native_restore_fl(),
native_irq_disable() and native_irq_enable() are equally referenced by
address in arch/x86/kernel/paravirt.c and thus should suffer from the
same problem. Can you explain?
