[patch] x86: convert rdtscll() to use __native_read_tsc

[Ken Chen]

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.
