[ARM] SMP: don't set cpu_*_map in smp_prepare_boot_cpu

2006-03-25T21:37:29Z

The recent addition of boot_cpu_init() implements the initialisation of the online, present and possible cpu maps for the boot CPU, so there is no reason to duplicate this in the architecture smp_prepare_boot_cpu() hook. Signed-off-by: Russell King

[ARM] Fix SMP initialisation oops

2006-02-16T11:08:09Z

A change to the SMP initialisation caused the following oops: CPU1: Booted secondary processor CPU1: D VIPT write-back cache CPU1: I cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets CPU1: D cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets <7>Calibrating delay loop... 83.14 BogoMIPS (lpj=415744) <1>Unable to handle kernel NULL pointer dereference at virtual address 0000001c ... PC is at enqueue_task+0x1c/0x64 LR is at activate_task+0xcc/0xe4 SMP initialisation now requires cpu_possible_map to be initialised in setup_arch(). Move this from smp_prepare_cpus() to smp_init_cpus() and call it from our setup_arch() if CONFIG_SMP is enabled. Signed-off-by: Russell King

[PATCH] sched: disable preempt in idle tasks

2005-11-09T15:56:33Z

Run idle threads with preempt disabled. Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()). How did it ever work before? Might fix the CPU hotplugging hang which Nigel Cunningham noted. We think the bug hits if the idle thread is preempted after checking need_resched() and before going to sleep, then the CPU offlined. After calling stop_machine_run, the CPU eventually returns from preemption and into the idle thread and goes to sleep. The CPU will continue executing previous idle and have no chance to call play_dead. By disabling preemption until we are ready to explicitly schedule, this bug is fixed and the idle threads generally become more robust.
