o Rename ic_eoi to ic_clear to emphasize the functions it points
don't send and EOI which works like on amd64/i386 and blocks all interrupts on the relevant interrupt controller. o Replace the post_filter and post_inthread hooks registered when creating the interrupt events with just ic_clear as on sparc64 we don't need to do any disable->EOI->enable dance to unblock all but the relevant interrupt while running the filter or handler; just not clearing the interrupt already has the same effect. o Merge from amd64/i386: - Split the intr_table_lock into an sx lock used for most things, and a spin lock to protect intrcnt_index. - Add support for binding interrupts to CPUs, including for the bus_bind_intr(9) interface, a assign_cpu hook and initially shuffling interrupts arround in a round-robin fashion.
