Subject: [PATCH 0/2 v2] Move SEV sysfs information and expose MSR_SEV_STATUS

From: Joerg Roedel <jroedel@...e.de>

Hi,

these changes move the SEV sysfs directory to /sys/hypervisor/ as
discussed on the mailing-list[1] and add an attribute to expose the
raw value of the SEV_STATUS MSR.

For compatibility reasons a symlink is created at the old location of
the directory to link the new location.

Regards,

	Joerg
