[PATCH] slab: Use same schedule timeout for all cpus in cache_reap

Chen noticed that cache_reap uses REAPTIMEOUT_CPUC+smp_processor_id() as
the timeout for rescheduling.

The "+smp_processor_id()" part is wrong, the timeout should be identical
for all cpus: start_cpu_timer already adds a cpu dependant offset to avoid
any clustering.

The attached patch removes smp_processor_id().
