Merge branch 'fixes' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm bugfixes from Gleb Natapov:
 "There is one more fix for MIPS KVM ABI here, MIPS and PPC build
  breakage fixes and a couple of PPC bug fixes"

* 'fixes' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
  kvm/ppc/booke64: Fix lazy ee handling in kvmppc_handle_exit()
  kvm/ppc/booke: Hold srcu lock when calling gfn functions
  kvm/ppc/booke64: Disable e6500 support
  kvm/ppc/booke64: Fix AltiVec interrupt numbers and build breakage
  mips/kvm: Use KVM_REG_MIPS and proper size indicators for *_ONE_REG
  kvm: Add definition of KVM_REG_MIPS
  KVM: add kvm_para_available to asm-generic/kvm_para.h
