#     crypto: x86/aegis,morus - Fix and simplify CPUID checks
#     
#     It turns out I had misunderstood how the x86_match_cpu() function works.
#     It evaluates a logical OR of the matching conditions, not logical AND.
#     This caused the CPU feature checks for AEGIS to pass even if only SSE2
#     (but not AES-NI) was supported (or vice versa), leading to potential
#     crashes if something tried to use the registered algs.
#     
#     This patch switches the checks to a simpler method that is used e.g. in
#     the Camellia x86 code.
#     
#     The patch also removes the MODULE_DEVICE_TABLE declarations which
#     actually seem to cause the modules to be auto-loaded at boot, which is
#     not desired. The crypto API on-demand module loading is sufficient.
#     
#     Fixes: 1d373d4e8e15 ("crypto: x86 - Add optimized AEGIS implementations")
#     Fixes: 6ecc9d9ff91f ("crypto: x86 - Add optimized MORUS implementations")
