crypto: ghash-generic - move common definitions to a new header file
commit a397ba8 upstream. Move common values and types used by ghash-generic to a new header file so drivers can directly use ghash-generic as a fallback implementation. Fixes: cc333cd ("crypto: vmx - Adding GHASH routines for VMX module") Signed-off-by: Marcelo Cerri <marcelo.cerri@canonical.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
