Date: Fri, 21 Oct 2016 11:16:12 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Marcelo Cerri <marcelo.cerri@...onical.com>, Herbert Xu <herbert@...dor.apana.org.au> Subject: [PATCH 4.4 21/25] crypto: ghash-generic - move common definitions to a new header file 4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Marcelo Cerri <marcelo.cerri@...onical.com> commit a397ba829d7f8aff4c90af3704573a28ccd61a59 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.
