Milton Miller 6e6b44e822 [POWERPC] Timer interrupt: use a struct for two per_cpu varables
timer_interrupt() was calculating per_cpu_offset several times, having to
start from the toc because of potential aliasing issues.

Placing both decrementer per_cpu varables in a struct and calculating
the address once with __get_cpu_var results in better code on both 32
and 64 bit.
