Cliff Wickman c8217b8305 x86, paravirt: Use native_halt on a halt, not native_safe_halt ... halt() should use native_halt() safe_halt() uses native_safe_halt() If CONFIG_PARAVIRT=y, halt() is defined in arch/x86/include/asm/paravirt.h as static inline void halt(void) { PVOP_VCALL0(pv_irq_ops.safe_halt); } Otherwise (no CONFIG_PARAVIRT) halt() in arch/x86/include/asm/irqflags.h is static inline void halt(void) { native_halt(); } So it looks to me like the CONFIG_PARAVIRT case of using native_safe_halt() for a halt() is an oversight. Am I missing something? It probably hasn't shown up as a problem because the local apic is disabled on a shutdown or restart. But if we disable interrupts and call halt() we shouldn't expect that the halt() will re-enable interrupts.
