From: Mickaël Salaün <mic@xxxxxxxxxxxxxxxxxxx> Wire up trusted_for(2) for all architectures. Cc: Al Viro <viro@xxxxxxxxxxxxxxxxxx> Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: Kees Cook <keescook@xxxxxxxxxxxx> Signed-off-by: Mickaël Salaün <mic@xxxxxxxxxxxxxxxxxxx> Reviewed-by: Thibaut Sautereau <thibaut.sautereau@xxxxxxxxxxx> Acked-by: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> --- Changes since v11: * Add Acked-by: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> * Rebase and leave space for watch_mount(2) and epoll_pwait2(2) from -next. Changes since v9: * Rename introspect_access(2) to trusted_for(2). * Increase syscall number to leave space for memfd_secret(2) in -next. Changes since v7: * New patch for the new syscall. * Increase syscall numbers by 2 to leave space for new ones (in linux-next): watch_mount(2) and process_madvise(2). ---
