    Subject[PATCH v5 00/12] x86: Support Key Locker
    Date
    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
