H A Darch_timer.hdiff db26f8f2da92471e9f7f71ec78d6fa455cd9c821 Sun Oct 17 07:42:21 CDT 2021 Marc Zyngier <maz@kernel.org> clocksource/drivers/arch_arm_timer: Move workaround synchronisation around

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.
