kaf24@firebug.cl.cam.ac.uk 88490a29fe Propagate guest MSR writes to machine MSRs immediately 
Right now, we have an exposure between the time the MSR is written
and used by an instruction such as syscall. If there is a context
switch and we do vmx_do_restore_msrs(), everything goes fine. But
if we don't, then we execute the syscall with the wrong MSR.

kaf24@firebug.cl.cam.ac.uk bbb0eb3225 First cut of new time interfaces and synchronisation mechanisms. 
Based on an initial patch from Don Fry at IBM.
Still TODO: 
 1. Testing
 2. NTP synchronisation
 3. Fix wallclock interface a bit
 4. Support for platform timers other than PIT (e.g., HPET, IBM Cyclone)
 5. Scale 64-bit TSC diffs instead of 32-bit, just for sanity
 6. Error-correcting scale factor is still slightly wrong
 6. More testing
