If CPU_FTR_PURR is not set, we will never set cpu_purr_data->initialized. Checking via __get_cpu_var on 64 bit avoids one dependent load compared to cpu_has_feature in the not-present case, and is always required when it is present. The code is under CONFIG_VIRT_CPU_ACCOUNTING so 32 bit will not be affected. Signed-off-by: NMilton Miller <miltonm@bga.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>
