x86: convert rdtscll() to use __native_read_tsc
Impact: micro-optimization Is there any reason why x86 rdtscll have to use the out of line function instead of inline __native_read_tsc()? native_read_tsc and __native_read_tsc is essentially the same functions. Patch to let x86 rdtscll() to use the inline version of read_tsc. Signed-off-by: Ken Chen <kenchen@google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
