* ARM: mx5: dynamically allocate imx-keypad devicesFabio Estevam2011-01-129-28/+17
| | | | | | | | | | | | | | | Add support for dynamical allocation of imx-keypad on mx5 platform. After moving to dynamically registration of the keypad, the keypad clock name needs to change accordingly. The reason is that the original mx5 keypad platform_device id was 0, now we use id=-1 as per arch/arm/plat-mxc/devices/platform-imx-keypad.c. Tested keypad successfully on a MX51_3DS board.

* ARM: mxs: Change duart device to use amba-pl011Shawn Guo2011-01-1211-68/+88
| | | | | | | | | The mxs duart is actually an amba-pl011 device. This commit changes the duart device code to dynamically allocate amba-pl011 device, so that drivers/serial/amba-pl011.c can be used on mxs.

When a cpu gets offlined it schedules the idle process which, before killing its own cpu, will call tick_nohz_stop_sched_tick(). That function in turn will call arch_needs_cpu() in order to check if the local tick can be disabled. On offline cpus this function should naturally return 0 since regardless if the tick gets disabled or not the cpu will be dead short after. That is besides the fact that __cpu_disable() should already have made sure that no interrupts on the offlined cpu will be delivered anyway. In this case it prevents tick_nohz_stop_sched_tick() to call select_nohz_load_balancer(). No idea if that really is a problem. However what made me debug this is that on 2.6.32 the function get_nohz_load_balancer() is used within __mod_timer() to select a cpu on which a timer gets enqueued. If arch_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn't get updated when a cpu gets offlined. It may contain the cpu number of an offline cpu. In turn timers get enqueued on an offline cpu and not very surprisingly they never expire and cause system hangs. This has been observed 2.6.32 kernels. On current kernels __mod_timer() uses get_nohz_timer_target() which doesn't have that problem. However there might be other problems because of the too early exit tick_nohz_stop_sched_tick() in case a cpu goes offline. This specific bug was indrocuded with 3c5d92a0 "nohz: Introduce arch_needs_cpu". In this case a cpu hotplug notifier is used to fix the issue in order to keep the normal/fast path small. All we need to do is to clear the condition that makes arch_needs_cpu() return 1 since it is just a performance improvement which is supposed to keep the local tick running for a short period if a cpu goes idle. Nothing special needs to be done except for clearing the condition.
