Patch series "selftests, powerpc, x86: Memory Protection Keys", v19. Memory protection keys enables an application to protect its address space from inadvertent access by its own code. 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). This patch (of 24): Move selftest files from tools/testing/selftests/x86/ to tools/testing/selftests/vm/.
