Stefan Roese 3e7b484354 powerpc: Fix decrementer setup on 1GHz boards ... We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX boards anymore. As it seems, patch 8d165db1 [powerpc: Improve decrementer accuracy] introduced this problem. The routine div_sc() overflows with shift = 32 resulting in this incorrect setup: time_init: decrementer frequency = 1000.000012 MHz time_init: processor frequency = 1000.000012 MHz clocksource: timebase mult[400000] shift[22] registered clockevent: decrementer mult[33] shift[32] cpu[0] This patch now introduces a local div_dc64() version of this function so that this overflow doesn't happen anymore.
