clocksource/drivers/arch_arm_timer: Move workaround synchronisation around
mainline inclusion from mainline-v5.16-rc1 commit db26f8f2 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4QCBG CVE: NA ---------------------- We currently handle synchronisation when workarounds are enabled by having an ISB in the __arch_counter_get_cnt?ct_stable() helpers. While this works, this prevents us from relaxing this synchronisation. Instead, move it closer to the point where the synchronisation is actually needed. Further patches will subsequently relax this.
