Subject: [GIT PULL] x86/paravirt changes for v4.20
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
