Subject: hrtimers: Make struct hrtimer_cpu_base layout less stupid
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f24444b01bf6c51c300fd3ffc73423383d747882;p=openwrt%2Fstaging%2Fblogic.git

hrtimers: Make struct hrtimer_cpu_base layout less stupid

In the HIGHRES=y case we access the members at the end of struct
hrtimer_cpu_base first and then the one at the beginning. Move the
hrtimer data to front, so we have linear progressing access.
