Andy Lutomirski 03b9730b76 x86/asm/tsc: Add rdtsc_ordered() and use it in trivial call sites ... rdtsc_barrier(); rdtsc() is an unnecessary mouthful and requires more thought than should be necessary. Add an rdtsc_ordered() helper and replace the trivial call sites with it. This should not change generated code. The duplication of the fence asm is temporary.
