-Subject: [PATCH 02/31] x86/sgx: Add wrapper for SGX2 EMODPR function
-
-Add a wrapper for the EMODPR ENCLS leaf function used to
-restrict enclave page permissions as maintained in the
-SGX hardware's Enclave Page Cache Map (EPCM).
-
-EMODPR:
-1) Updates the EPCM permissions of an enclave page by treating
-   the new permissions as a mask. Supplying a value that attempts
-   to relax EPCM permissions has no effect on EPCM permissions
-   (PR bit, see below, is changed).
-2) Sets the PR bit in the EPCM entry of the enclave page to
-   indicate that permission restriction is in progress. The bit
-   is reset by the enclave by invoking ENCLU leaf function
-   EACCEPT or EACCEPTCOPY.
-
-The enclave may access the page throughout the entire process
-if conforming to the EPCM permissions for the enclave page.
-
-After performing the permission restriction by issuing EMODPR
-the kernel needs to collaborate with the hardware to ensure that
-all logical processors sees the new restricted permissions. This
-is required for the enclave's EACCEPT/EACCEPTCOPY to succeed and
-is accomplished with the ETRACK flow.
-
-Expand enum sgx_return_code with the possible EMODPR return
-values.
