[PATCH] fix memory leak in acpi-cpufreq

[Luming Yu]

Hi there,

I came across a memory leak problem found in cyclic cpu-online-offline test.
The inlined patch simple does this to fix it.

> b/drivers/cpufreq/acpi-cpufreq.c
>static void __exit acpi_cpufreq_exit(void)
>  	cpufreq_unregister_driver(&acpi_cpufreq_driver);
> -	free_percpu(acpi_perf_data);
>+	free_acpi_perf_data();

Ps. The patch is enclosed in attachment. The inline one
is c&p of it for reading.


Thanks,
Luming
