Hi All

My test results are as follows:

before this patch:

[ 49.919574] softirq: huh, entered softirq 1 TIMER 00000000bb45ef3a with preempt_count 00000101, exited with 00000101?


after this patch:

[ 49.919570] softirq: huh, entered softirq 1 TIMER run_timer_softirq+0x0/0x108 with preempt_count 00000101, exited with 00000102?

preempt_count_set(prev_count);
