John Baldwin 7ff829cb0e Lock iir(4) and mark it MPSAFE. ... - Add a per-device mutex to the softc and use it for bus_dma tags, CAM SIMs, callouts, and interrupt handler. - Switch from timeout(9) to callout(9). - Add a separate global mutex to protect the global event buffer ring. - Return completed index from iir_intr_locked() and remove the global gdt_wait_* variables. - Remove global list of gdt softcs and replace its use with devclass_get_device(). - Use si_drv1 to store softc pointer in the SDEV_PER_HBA case instead of minor numbers. - Do math on osreldate instead of dubious char math on osrelease[] that didn't work on 10.0+. - Use bus_*() instead of bus_space_*(). - Use device_printf() instead of printf() with a unit number.
