Subject: [PATCH] x86/crypto: Add missing RETs

Add explicit RETs to the tail calls of AEGIS and MORUS crypto algorithms
otherwise they run into INT3 padding due to

  51bad67ffbce ("x86/asm: Pad assembly functions with INT3 instructions")

leading to spurious debug exceptions.

Mike Galbraith [off-list ref] took care of all the remaining callsites.

Signed-off-by: Borislav Petkov <redacted>
Patch applied.  Thanks.
