[PATCH v6 0/3] SED OPAL Library

[Scott Bauer]

Changes from v5->v6:

1) Fixed comments from last review From Christoph
2) Rebased code on top of Jens' for-next
3) Explicitly aligned the structs in the uapi

===============================================================================
This Patch series implements a large portion of the Opal protocol for
self encrypting devices. The driver has the capability of storing a
locking range's password. The password can then be replayed
during a resume from previous suspend-to-RAM.

The driver also supports logic to bring the device out of a factory
default-inactive state into a functional Opal state.

The following logic is supported in order to bring the tper into a
working state:

1) Taking Ownership of the drive (Setting the Admin CPIN).
2) Activating the Locking SP (In Single User Mode or Normal Mode).
3) Setting up Locking Ranges (Single User or Normal Mode).
4) Adding users to Locking Ranges (Normal Mode Only).
5) Locking or Unlocking Locking Ranges (Single User Mode or Normal Mode).
6) Reverting the TPer (Restore to factory default).
7) Setting LR/User passwords (Single User Mode or Normal Mode).
8) Enabling/disabling Shadow MBR.
9) Enabling Users in the LockingSP (Normal Mode Only).
10) Saving Password for resume from suspend.
11) Erase and Secure erasing locking ranges.

  Include: Uapi: Add user ABI for Sed/Opal
  block: Add Sed-opal library
  nvme: Add Support for Opal: Unlock from S3 & Opal Allocation/Ioctls
