Andrew Morton 02d2116887 revert "percpu_counter: new function percpu_counter_sum_and_set" 
Revert

    commit e8ced39d5e
    Author: Mingming Cao <cmm@us.ibm.com>

        percpu_counter: new function percpu_counter_sum_and_set

As described in

	revert "percpu counter: clean up percpu_counter_sum_and_set()"

the new percpu_counter_sum_and_set() is racy against updates to the
cpu-local accumulators on other CPUs.  Revert that change.

This means that ext4 will be slow again.  But correct.
