allows all the INTR_FILTER #ifdef's to be removed from the MD interrupt code. - Rename the intr_event 'eoi', 'disable', and 'enable' hooks to 'post_filter', 'pre_ithread', and 'post_ithread' to be less x86-centric. Also, add a comment describe what the MI code expects them to do. - On amd64, i386, and powerpc this is effectively a NOP. - On arm, don't bother masking the interrupt unless the ithread is scheduled in the non-INTR_FILTER case to match what INTR_FILTER did. Also, don't bother unmasking the interrupt in the post_filter case if we never masked it. The INTR_FILTER case had been doing this by having arm_unmask_irq for the post_filter (formerly 'eoi') hook. - On ia64, stray interrupts are now masked for the non-INTR_FILTER case. They were already masked in the INTR_FILTER case. - On sparc64, use the a NULL pre_ithread hook and use intr_enable_eoi() for both the 'post_filter' and 'post_ithread' hooks to match what the non-INTR_FILTER code did. - On sun4v, retire the ithread wrapper hack by using an appropriate 'post_ithread' hook instead (it's what 'post_ithread'/'enable' was designed to do even in 5.x).
