Linus,

# HEAD: 3a025de64bf89c84a79909069e3c24ad9e710d27 x86/hyperv: Enable PV qspinlock for Hyper-V
Two main changes:
- Remove no longer parts of the paravirt infrastructure and put large quantities of paravirt ops under a new config option PARAVIRT_XXL=y, which is selected by XEN_PV only. (Joergen Gross)
- Enable PV spinlocks on Hyperv (Yi Sun)
Thanks,
Ingo
