Helge Deller afdb4a5b1d parisc: Mark cr16 CPU clocksource unstable on all SMP machines ... In commit c8c3735997 ("parisc: Enhance detection of synchronous cr16 clocksources") I assumed that CPUs on the same physical core are syncronous. While booting up the kernel on two different C8000 machines, one with a dual-core PA8800 and one with a dual-core PA8900 CPU, this turned out to be wrong. The symptom was that I saw a jump in the internal clocks printed to the syslog and strange overall behaviour. On machines which have 4 cores (2 dual-cores) the problem isn't visible, because the current logic already marked the cr16 clocksource unstable in this case. This patch now marks the cr16 interval timers unstable if we have more than one CPU in the system, and it fixes this issue.
