Subject: [PATCH v5 00/12] x86: Support Key Locker
Date:   Wed, 12 Jan 2022 13:12:46 -0800
Message-Id: <20220112211258.21115-1-chang.seok.bae@intel.com>
Precedence: bulk

Changes from v4 [1]:
* Drop CBC mode support (PATCH10). (Eric Biggers)
* Update the changelog (PATCH8). (Rafael Wysocki)

A couple of other things outside of these patches are still in progress:
* Support DM-crypt/cryptsetup for Key Locker usage (Andy Lutomirski)
  [2].
* Understand decryption under-performance (Eric Biggers and Milan Broz)
  [3][4].

This feature's usage for the threat model can be found in the previous
cover letter [1]. This version is based on 5.16.

Thanks,
Chang
