[PATCH 4.17 44/45] crypto: vmx - Remove overly verbose printk from AES XTS init

From: Greg Kroah-Hartman
Date: Thu Jun 14 2018 - 10:51:26 EST

4.17-stable review patch. If anyone has any objections, please let me know.


From: Michael Ellerman <mpe@xxxxxxxxxxxxxx>

commit 730f23b66095a700e2f0786abda6bca011b31558 upstream.

In p8_aes_xts_init() 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. So remove it.
