x86: split get_cycles_sync
This patch splits get_cycles_sync() into __get_cycles_sync(), and the rdtscll part. Paravirt guests cannot issue rdtscl directly, as it involves a function call in vdso area. So, using the __get_cycles_sync() base, we introduce vget_cycles_sync, which then calls the native version of rdtscll. Ideally, however, a guest should define its own clocksource, together with a vread function Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
