[PATCH] x86: Use RDTSCP for synchronous get_cycles if possible
RDTSCP is already synchronous and doesn't need an explicit CPUID.
This is a little faster and more importantly avoids VMEXITs on Hypervisors.
Original patch from Joerg Roedel, but reworked by AK
Also includes miscompilation fix by Eric Biederman
