[ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCore 2008-02-04T17:52:19+00:00 Catalin Marinas catalin.marinas@arm.com 2008-02-04T16:30:57+00:00 a8655e83fc44ec2b92cbea9f3ff3cc0da05a991c This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer.

SMP initialisation now requires cpu_possible_map to be initialised in
setup_arch().  Move this from smp_prepare_cpus() to smp_init_cpus()
