Subject: [PATCH 0/2] s390: Autoload uvdevice module based on CPU feature

Currently, the uvdevice (drivers/s390/char/uvdevice) must be loaded
manually. We can, however, determine if the Ultravisor is available
by observing facility 158. 

This series, first, introduces the HWCAP_UV connected to facility 158.
And, second, it automatically loads the uvdevice if HWCAP_UV is present.
