This patch series is to allow the kernel space to create and manage a single hardware session (a.k.a. default session or arbitrary session). So user can allocate the protected buffer, which is encrypted with the leverage of the arbitrary hardware session. rev23: #09, #12 - Require user space to explicitly set recoverable flag to false for protected context creation. #13 - Add Cc of reviewers in commit message.
