Steve,

to make it compile and build replace
 arch/x86_64/kernel/smpboot.c: line 191
with this:
<snip>
static __cpuinitdata raw_spinlock_t tsc_sync_lock = RAW_SPIN_LOCK_UNLOCKED;
</snip>

or alternativly:
<snip>
static DEFINE_RAW_SPINLOCK(tsc_sync_lock);
</snip>

    Karsten

Thanks Karsten,

That fixed it. Though now my bleeding edge InfiniBand driver is 
complaining about SPIN_LOCK_UNLOCKED being undeclared. Could this be 
caused by the preemt patch, as the IB driver compiles against an 
unpatched kernel. I'll look into further.

Cheers,

Steve.
