  KVM: ia64: Fix irq disabling leak in error handling code
  KVM: VMX: Fix undefined beaviour of EPT after reload kvm-intel.ko
  KVM: VMX: Fix bypass_guest_pf enabling when disable EPT in module parameter
  KVM: task switch: translate guest segment limit to virt-extension byte granular field
  KVM: Avoid instruction emulation when event delivery is pending
  KVM: task switch: use seg regs provided by subarch instead of reading from GDT
  KVM: task switch: segment base is linear address
  KVM: SVM: allow enabling/disabling NPT by reloading only the architecture module
