[ACPI] update C-state limiting patch
Now "max_cstate=" instead of "acpi_cstate_limit="
Delete redundant static cstate flags .c2 and .c3
http://bugme.osdl.org/show_bug.cgi?id=3549
For static processor driver, boot cmdline:
processor.max_cstate=2
For processor module, /etc/modprobe.conf:
options processor max_cstate=2
or
# modprobe processor max_cstate=2
From kernel or kernel module:
#include <linux/acpi.h>
acpi_set_cstate_limit(2);
