Subject: [PATCH 00/12] KVM: X86: misc fixes and cleanup

From: Lai Jiangshan <laijs@...ux.alibaba.com>

This pacheset has misc fixes and cleanups with loose dependence to each
other.  It includes a prevous patch that inverts and renames
gpte_is_8_bytes.

Ohter patches focus on the usage of vcpu->arch.walk_mmu and
vcpu->arch.mmu, root_level, lpage_level.

Patch 1,4,5,6,7 fixes something, but I don't think path4,5,6,7 are worth
in stable tree.

Lai Jiangshan (12):
  KVM: X86: Fix when shadow_root_level=5 && guest root_level<4
  KVM: X86: Add parameter struct kvm_mmu *mmu into mmu->gva_to_gpa()
  KVM: X86: Remove mmu->translate_gpa
  KVM: X86: Use vcpu->arch.walk_mmu for kvm_mmu_invlpg()
  KVM: X86: Change the type of a parameter of kvm_mmu_invalidate_gva()
    and mmu->invlpg() to gpa_t
  KVM: X86: Add huge_page_level to __reset_rsvds_bits_mask_ept()
  KVM: X86: Add parameter huge_page_level to kvm_init_shadow_ept_mmu()
  KVM: VMX: Use ept_caps_to_lpage_level() in hardware_setup()
  KVM: X86: Rename gpte_is_8_bytes to has_4_byte_gpte and invert the
    direction
  KVM: X86: Remove mmu parameter from load_pdptrs()
  KVM: X86: Check root_level only in fast_pgd_switch()
  KVM: X86: Walk shadow page starting with shadow_root_level
