Ryan Moeller e0716250bf FreeBSD: Do zcommon_init sooner to avoid FPU panic ... There has been a panic affecting some system configurations where the thread FPU context is disturbed during the fletcher 4 benchmarks, leading to a panic at boot. module_init() registers zcommon_init to run in the last subsystem (SI_SUB_LAST). Running it as soon as interrupts have been configured (SI_SUB_INT_CONFIG_HOOKS) makes sure we have finished the benchmarks before we start doing other things. While it's not clear *how* the FPU context was being disturbed, this does seem to avoid it. Add a module_init_early() macro to run zcommon_init() at this earlier point on FreeBSD. On Linux this is defined as module_init().
