Gideon Israel Dsouza d8c34b949d crypto: Replaced gcc specific attributes with macros from compiler.h
Continuing from this commit: 52f5684c8e
("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.

Andrzej Zaborowski 28a4618ad1 crypto: akcipher - add akcipher declarations needed by templates.
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.

David Howells 381ceef785 crypto: akcipher - Don't #include crypto/public_key.h as the contents aren't used
Don't #include crypto/public_key.h in akcipher as the contents of the
header aren't used and changes in a future patch cause it to fail to
compile if CONFIG_KEYS=n.
