| |
Currently, the ARM backend must maintain a redundant list of timers for the purpose of centralising timer broadcast functionality. This prevents sharing timer drivers across architectures.
This patch moves the pain of dealing with timer broadcasts to the core clockevents tick broadcast code, which already maintains its own list of timers.
