Tao Su db574f2f96 KVM: x86/mmu: Don't save mmu_invalidate_seq after checking private attr ... Drop the second snapshot of mmu_invalidate_seq in kvm_faultin_pfn(). Before checking the mismatch of private vs. shared, mmu_invalidate_seq is saved to fault->mmu_seq, which can be used to detect an invalidation related to the gfn occurred, i.e. KVM will not install a mapping in page table if fault->mmu_seq != mmu_invalidate_seq. Currently there is a second snapshot of mmu_invalidate_seq, which may not be same as the first snapshot in kvm_faultin_pfn(), i.e. the gfn attribute may be changed between the two snapshots, but the gfn may be mapped in page table without hindrance. Therefore, drop the second snapshot as it has no obvious benefits.
