This commit addresses several multiprocessing issues in base-hw: * it reworks cross-cpu maintainance work for TLB invalidation by introducing a generic Inter_processor_work and removes the so called Cpu_domain_update * thereby it solves the cross-cpu thread destruction, when the corresponding thread is active on another cpu (fix #3043) * it adds the missing TLB shootdown for x86 (fix #3042) * on ARM it removes the TLB shootdown via IPIs, because this is not needed on the multiprocessing ARM platforms we support * it enables the per-cpu initialization of the kernel's cpu objects, which means those object initialization is executed by the proper cpu * it rollbacks prior decision to make multiprocessing an aspect, but puts back certain 'smp' mechanisms (like cross-cpu lock) into the generic code base for simplicity reasons |
