KVM: MMU: introduce kvm_mmu_gfn_{allow,disallow}_lpage
Abstract the common operations from account_shadowed() and unaccount_shadowed(), then introduce kvm_mmu_gfn_disallow_lpage() and kvm_mmu_gfn_allow_lpage() These two functions will be used by page tracking in the later patch Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
