Subject: [PATCH 00/12] KVM: X86/MMU: Simpliy mmu_unsync_walk()

From: Lai Jiangshan <jiangshan.ljs@...group.com>

mmu_pages_clear_parents() is not really required (see patch4).

mmu_unsync_walk() can be simplified when the function is removed.

Lai Jiangshan (12):
  KVM: X86/MMU: Warn if sp->unsync_children > 0 in link_shadow_page()
  KVM: X86/MMU: Rename kvm_unlink_unsync_page() to
    kvm_mmu_page_clear_unsync()
  KVM: X86/MMU: Split a part of kvm_unsync_page() as
    kvm_mmu_page_mark_unsync()
  KVM: X86/MMU: Remove mmu_pages_clear_parents()
  KVM: X86/MMU: Clear unsync bit directly in __mmu_unsync_walk()
  KVM: X86/MMU: Rename mmu_unsync_walk() to mmu_unsync_walk_and_clear()
  KVM: X86/MMU: Remove the useless struct mmu_page_path
  KVM: X86/MMU: Remove the useless idx from struct kvm_mmu_pages
  KVM: X86/MMU: Unfold struct mmu_page_and_offset in struct
    kvm_mmu_pages
  KVM: X86/MMU: Don't add parents to struct kvm_mmu_pages
  KVM: X86/MMU: Remove mmu_pages_first() and mmu_pages_next()
  KVM: X86/MMU: Rename struct kvm_mmu_pages to struct kvm_mmu_page_vec
