This feature is now enabled on powerpc and has been available since 4.16-rc1. The patches move the selftests to arch neutral directory and enhance their test coverage. Tested on powerpc64 and x86_64 (Skylake-SP). Changelog --------- Link to previous version (v15): https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=149238 v16: (1) Rebased on top of latest master. (2) Switched to u64 instead of using an arch-dependent pkey_reg_t type for references to the pkey register based on suggestions from Dave, Michal and Michael. (3) Removed build time determination of page size based on suggestion from Michael. (4) Fixed comment before the definition of __page_o_noops() from patch 13 ("selftests/vm/pkeys: Introduce powerpc support"). v15: (1) Rebased on top of latest master. (2) Addressed review comments from Dave Hansen. (3) Moved code for getting or setting pkey bits to new helpers. These changes replace patch 7 of v14. (4) Added a fix which ensures that the correct count of reserved keys is used across different platforms. (5) Added a fix which ensures that the correct page size is used as powerpc supports both 4K and 64K pages. v14: (1) Incorporated another round of comments from Dave Hansen. v13: (1) Incorporated comments for Dave Hansen. (2) Added one more test for correct pkey-0 behavior. v12: (1) Fixed the offset of pkey field in the siginfo structure for x86_64 and powerpc. And tries to use the actual field if the headers have it defined. v11: (1) Fixed a deadlock in the ptrace testcase. v10 and prior: (1) Moved the testcase to arch neutral directory. (2) Split the changes into incremental patches. Desnes A.
