commit 1411b5218a upstream.
In the vmx AES init routines we do a printk(KERN_INFO ...) to report
the fallback implementation we're using.
However with a slow console this can significantly affect the speed of
crypto operations. Using 'cryptsetup benchmark' the removal of the
printk() leads to a ~5x speedup for aes-cbc decryption.
So remove them.
