Subject: timer_list: print cpu number of clockevents device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c5b77a3d3a716a5c61a1999d7f2a78e9c39fd1b0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

timer_list: print cpu number of clockevents device

The per cpu clock events device output of timer_list lacks an
association of the device to the cpu which is annoying when looking at
the output of /proc/timer_list from a 128 way system.

Add the CPU number info and mark the broadcast device in the device
list printout.
