Michael Ellerman 5635242c85 crypto: vmx - Remove overly verbose printk from AES init routines 
commit 1411b5218adbcf1d45ddb260db5553c52e8d917c 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.
