#     crypto: x86 - Add missing RETs
#     
#     Add explicit RETs to the tail calls of AEGIS and MORUS crypto algorithms
#     otherwise they run into INT3 padding due to
#     
#       ("x86/asm: Pad assembly functions with INT3 instructions")
#     
#     leading to spurious debug exceptions.
#     
#     Mike Galbraith <efault@gmx.de> took care of all the remaining callsites.
