Masahiro Kozuka c8c340a9b4 KVM: SEV: Flush cache on non-coherent systems before RECEIVE_UPDATE_DATA ... Flush the destination page before invoking RECEIVE_UPDATE_DATA, as the PSP encrypts the data with the guest's key when writing to guest memory. If the target memory was not previously encrypted, the cache may contain dirty, unecrypted data that will persist on non-coherent systems.
