  Message : clockintr: switch from callee- to caller-allocated clockintr structs Currently, clockintr_establish() calls malloc(9) to allocate a clockintr struct on behalf of the caller. mpi@ says this behavior is incompatible with dt(4). In particular, calling malloc(9) during the initialization of a PCB outside of dt_pcb_alloc() is (a) awkward and (b) may conflict with future changes/optimizations to PCB allocation. To side-step the problem, this patch changes the clockintr subsystem to use caller-allocated clockintr structs instead of callee-allocated structs. clockintr_establish() is named after softintr_establish(), which uses malloc(9) internally to create softintr objects. The clockintr subsystem is no longer using malloc(9), so the "establish" naming is no longer apt. To avoid confusion, this patch also renames "clockintr_establish" to "clockintr_bind". Requested by mpi@. Tweaked by mpi@. Thread: https://marc.info/?l=openbsd-tech&m=170597126103504&w=2 ok claudio@ mlarkin@ mpi@
