These two patches try to improve the dw_apb_timer clocksource/clockevent performance.
since v2: - only use relaxed version in critical path - inline apbt_readl/apbt_writel - add some performance numbers
since v1: - correct the wrong sentence in commit msg about writel performance on CA9 with outer L2 cache. Thank Arnd for pointing out this in another thread.
Jisheng Zhang (2): clocksource/drivers/dw_apb_timer: Inline apbt_readl and apbt_writel clocksource/drivers/dw_apb_timer: Use {readl|writel}_relaxed in critical path
