Ville Juven 4959e269d6 sched/sem_waitirq: Move kmm_map() call to sem_wait() ... The kernel mapping should be performed in sem_wait (thread level) as virtual memory mappings cannot be added from interrupt, at least for now. The reason? kmm_map() depends on mm_map_add(), which in turn uses a mutex for mutual exclusion. Using mutexes from interrupt level is not permitted. Mapping tcb->waitobj into kernel virtual memory directly in sem_wait() makes sense, since accessing tcb->waitobj via a user virtual address can lead to unexpected results (the wrong mappings can be in place).		2025-03-13 12:28:22 +08:00
