2017-01-13crypto: Replaced gcc specific attributes with macros from compiler.hGideon Israel Dsouza
Continuing from this commit: 52f5684c8e1e ("kernel: use macros from compiler.h instead of __attribute__((...))") I submitted 4 total patches. They are part of task I've taken up to increase compiler portability in the kernel. I've cleaned up the subsystems under /kernel /mm /block and /security, this patch targets /crypto. There is <linux/compiler.h> which provides macros for various gcc specific constructs. Eg: __weak for __attribute__((weak)). I've cleaned all instances of gcc specific attributes with the right macros for the crypto subsystem. I had to make one additional change into compiler-gcc.h for the case when one wants to use this: __attribute__((aligned) and not specify an alignment factor. From the gcc docs, this will result in the largest alignment for that data type on the target machine so I've named the macro __aligned_largest. Please advise if another name is more appropriate.

2015-12-09crypto: akcipher - add akcipher declarations needed by templates.Andrzej Zaborowski
Add a struct akcipher_instance and struct akcipher_spawn similar to how AEAD declares them and the macros for converting to/from crypto_instance/crypto_spawn. Also add register functions to avoid exposing crypto_akcipher_type. Signed-off-by: Andrew Zaborowski <andrew.zaborowski@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
