Sean Christopherson 28b85ae06f KVM: Drop bogus "pfn != 0" guard from kvm_release_pfn() ... Remove a check from kvm_release_pfn() to bail if the provided @pfn is zero. Zero is a perfectly valid pfn on most architectures, and should not be used to indicate an error or an invalid pfn. The bogus check was added by commit 917248144d ("x86/kvm: Cache gfn to pfn translation"), which also did the bad thing of zeroing the pfn and gfn to mark a cache invalid. Thankfully, that bad behavior was axed by commit 357a18ad23 ("KVM: Kill kvm_map_gfn() / kvm_unmap_gfn() and gfn_to_pfn_cache").
