Author: marius Date: Mon Jul 25 18:24:17 2011 New Revision: 224359 URL: http://svn.freebsd.org/changeset/base/224359 Log: MFC: r223235 - As with stray vector interrupts limit the reporting of stray level interrupts. Bringup on additional machine models repeatedly reveals firmware that enables interrupts behind our back, causing the console to be flooded otherwise. - As with the regular interrupt counters using uint16_t instead of u_long for counting the stray vector interrupts should be more than sufficient. - Cache the interrupt vector in intr_stray_vector().
