elsewhere too sooner or later.

But it's *not* inlined by GCC or Clang.

While the function is marked `static inline`, it's not in
arch/x86/kernel/paravirt.o due to:
arch/x86/kernel/paravirt.c:326

325 __visible struct pv_irq_ops pv_irq_ops = {

326         .save_fl = __PV_IS_CALLEE_SAVE(native_save_fl),

see comparison of disassembly  attached in:
