[PATCH 1/2] crypto: vmx - Remove overly verbose printk from AES init routines

2018-05-03 Thread Michael Ellerman
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 decryp
