Subject[PATCH] 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 blackfin,
m68k, and xtensa have implemented it.

1. This fixes a regression in 2.6.32.
2. Long-time build issues like this make linux-next miss newer build
problems.

when I'm talking to journalists I just say "programmer" or something like that.
