[PATCH] x86: move turbo_disabled() out of intel_set_max_freq_ratio

move the turbo_disabled before intel_set_max_freq_ratio, when turbo is disabled, the max frequency ratio is a const value, it is unnecessary to read MSR_TURBO_RATIO* msr to compute Signed-off-by: Li RongQing --- arch/x86/kernel/smpboot.c | 5 - 1 file changed, 4 insertions(+), 1 deletion(-)
