commit 3e14dcf7cb80b34a1f38b55bc96f02d23fdaaaaf upstream.
Commit 5d26a105b5a7 ("crypto: prefix module autoloading with "crypto-"")
changed the automatic module loading when requesting crypto algorithms
to prefix all module requests with "crypto-". This requires all crypto
modules to have a crypto specific module alias even if their file name
would otherwise match the requested crypto algorithm.
Even though commit 5d26a105b5a7 added those aliases for a vast amount of
modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO
annotations to those files to make them get loaded automatically, again.
This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work
with kernels v3.18 and below.
Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former
won't work for crypto modules any more.

commit 5d26a105b5a73e5635eae0629b42fa0a90e07b7b upstream.
This prefixes all crypto module loading with "crypto-" so we never run
the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

When building with CRYPTO_SHA1_PPC enabled we fail with:

Use INT_FRAME_SIZE instead of STACKFRAMESIZE.

This patch adds a crypto driver which provides a powerpc accelerated
implementation of SHA-1, accelerated in that it is written in asm.
Original patch by Paul, minor fixups for upstream by moi.
Lightly tested on 64-bit with the test program here:
http://michael.ellerman.id.au/files/junkcode/sha1test.c
Seems to work, and is "not slower" than the generic version.
Needs testing on 32-bit.
