asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

gcc-11 points out a mismatch between the declaration and the definition
of poly1305_core_setkey():
lib/crypto/poly1305-donna32.c:13:67: error: argument 2 of type ‘const u8[16]’ {aka ‘const unsigned char[16]’} with mismatched bound [-Werror=array-parameter=]
13 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 raw_key[16])
| ~~~~~~~~~^~~~~~~~~~~
In file included from lib/crypto/poly1305-donna32.c:11:
include/crypto/internal/poly1305.h:21:68: note: previously declared as ‘const u8 *’ {aka ‘const unsigned char *’}
21 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 *raw_key);
This is harmless in principle, as the calling conventions are the same,
but the more specific prototype allows better type checking in the
caller.
Change the declaration to match the actual function definition.
The poly1305_simd_init() is a bit suspicious here, as it previously
had a 32-byte argument type, but looks like it needs to take the
16-byte POLY1305_BLOCK_SIZE array instead.
Fixes: 1c08a104360f ("crypto: poly1305 - add new 32 and 64-bit generic versions")

This appears to be some kind of copy and paste error, and is actually
dead code.
Pre: f = 0 ⇒ (f >> 32) = 0
f = (f >> 32) + le32_to_cpu(digest[0]);
Post: 0 ≤ f < 2³²
put_unaligned_le32(f, dst);
Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
f = (f >> 32) + le32_to_cpu(digest[1]);
Post: 0 ≤ f < 2³²
put_unaligned_le32(f, dst + 4);
Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
f = (f >> 32) + le32_to_cpu(digest[2]);
Post: 0 ≤ f < 2³²
put_unaligned_le32(f, dst + 8);
Pre: 0 ≤ f < 2³² ⇒ (f >> 32) = 0
f = (f >> 32) + le32_to_cpu(digest[3]);
Post: 0 ≤ f < 2³²
put_unaligned_le32(f, dst + 12);
Therefore this sequence is redundant. And Andy's code appears to handle
misalignment acceptably.

For glue code that's used by Zinc, the actual Crypto API functions might
not necessarily exist, and don't need to exist either. Before this
patch, there are valid build configurations that lead to a unbuildable
kernel. This fixes it to conditionalize those symbols on the existence
of the proper config entry.

This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for
MIPS authored by Andy Polyakov, a prior 64-bit only version of which has been
contributed by him to the OpenSSL project. The file 'poly1305-mips.pl' is taken
straight from this upstream GitHub repository [0] at commit
d22ade312a7af958ec955620b0d241cf42c37feb, and already contains all the changes
required to build it as part of a Linux kernel module.
