crypto: aesni-intel - Merge with fpu.ko
Loading fpu without aesni-intel does nothing. Loading aesni-intel
without fpu causes modes like xts to fail. (Unloading
aesni-intel will restore those modes.)
One solution would be to make aesni-intel depend on fpu, but it
seems cleaner to just combine the modules.
This is probably responsible for bugs like:
