Yes, you are right.
A little while back I backported the whole series to 2.6.32 and the
result was included the Jeremy's pvops main branch, but I haven't kept
it completely up to date.
The new changes that are only in the 2.6.35-rc5-pvhvm-v7 branch regards
PV spinlocks, the balloon driver and the PV console.
