The vSMP bits probably gathered some fuzz on its way to mainline, and safe_halt() which was outside the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition, hence being undefined and breaking CONFIG_X86_VSMP builds. Patch takes safe_halt() and halt() macros out of the #endif Signed-off-by: Ravikiran Thirumalai Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds --- diff --git a/include/asm-x86_64/system.h b/include/asm-x86_64/system.h index 0eacbefb7dd..a73f0c789d8 100644 --- a/include/asm-x86_64/system.h +++ b/include/asm-x86_64/system.h @@ -354,11 +354,6 @@ static inline unsigned long __cmpxchg(volatile void *ptr, unsigned long old, #define local_irq_disable() __asm__ __volatile__("cli": : :"memory") #define local_irq_enable() __asm__ __volatile__("sti": : :"memory") -/* used in the idle loop; sti takes one instruction cycle to complete */ -#define safe_halt() __asm__ __volatile__("sti; hlt": : :"memory") -/* used when interrupts are already enabled or to shutdown the processor */ -#define halt() __asm__ __volatile__("hlt": : :"memory") - #define irqs_disabled() \ ({ \ unsigned long flags; \ @@ -370,6 +365,11 @@ static inline unsigned long __cmpxchg(volatile void *ptr, unsigned long old, #define local_irq_save(x) do { warn_if_not_ulong(x); __asm__ __volatile__("# local_irq_save \n\t pushfq ; popq %0 ; cli":"=g" (x): /* no input */ :"memory"); } while (0) #endif +/* used in the idle loop; sti takes one instruction cycle to complete */ +#define safe_halt() __asm__ __volatile__("sti; hlt": : :"memory") +/* used when interrupts are already enabled or to shutdown the processor */ +#define halt() __asm__ __volatile__("hlt": : :"memory") + void cpu_idle_wait(void); extern unsigned long arch_align_stack(unsigned long sp);
