In arch/i386/kernel, inline asm for loading IDT (lidt) is used a few
times, but with slightly different constraints and output/input
definitions. Are these OK, equivalent, or what?
[rddunlap@dragon kernel]$ findc lidt
./cpu/common.c:484: __asm__ __volatile__("lidt %0": "=m" (idt_descr));
./traps.c:783: __asm__ __volatile__("lidt %0": "=m" (idt_descr));
vs.
./reboot.c:186: __asm__ __volatile__ ("lidt %0" : : "m" (real_mode_idt));
./reboot.c:261: __asm__ __volatile__("lidt %0": :"m" (no_idt));
./suspend.c:95: asm volatile ("lidt %0" :: "m" (saved_context.idt_limit));
Thanks,
