Dave Hansen caf9eb6b4c x86/pkeys/selftests: Avoid printf-in-signal deadlocks 
printf() and friends are unusable in signal handlers.  They deadlock.
The pkey selftest does not do any normal printing in signal handlers,
only extra debugging.  So, just print the format string so we get
*some* output when debugging.
