Keys: KEYCTL_SESSION_TO_PARENT needs TIF_NOTIFY_RESUME architecture support
As of commit ee18d64c1f632043a02e6f5ba5e045bb26a5465f ("KEYS: Add a keyctl to install a process's session keyring on its parent [try #6]"), CONFIG_KEYS=y fails to build on architectures that haven't implemented TIF_NOTIFY_RESUME yet: security/keys/keyctl.c: In function 'keyctl_session_to_parent': security/keys/keyctl.c:1312: error: 'TIF_NOTIFY_RESUME' undeclared (first use in this function) security/keys/keyctl.c:1312: error: (Each undeclared identifier is reported only once security/keys/keyctl.c:1312: error: for each function it appears in.) Make KEYCTL_SESSION_TO_PARENT depend on TIF_NOTIFY_RESUME until m68k, and xtensa have implemented it.
