Subject: [PATCH -next] crypto: fix aesni build on i386

From: Randy Dunlap <randy.dunlap@...cle.com>

Fix build error on i386 by moving function prototypes:

arch/x86/crypto/aesni-intel_glue.c: In function 'aesni_init':
arch/x86/crypto/aesni-intel_glue.c:1263: error: implicit declaration of function 'crypto_fpu_init'
arch/x86/crypto/aesni-intel_glue.c: In function 'aesni_exit':
arch/x86/crypto/aesni-intel_glue.c:1373: error: implicit declaration of function 'crypto_fpu_exit'

These function prototypes should preferably be in a header file somewhere.
