commit 729e15a864dd5b8d269fbb921c7254de51d9676c
Author: Sepherosa Ziehau <sephe at dragonflybsd.org>
Date:   Fri Jul 10 15:29:24 2009 +0800

    Use same interrupt vector handler for fast/slow interrupt handlers
    
    Slow interrupt vector handler is removed.  Fast interrupt vector handler,
    ithread_fast_handler(), now schedules slow interrupt handlers if necessary:
    o  No fast interrupt handlers are registered
    o  Mixed fast and slow interrpt handlers are registered
    o  Non-MPSAFE fast interrupt handlers could not get BGL
    
    i386/amd64: gd_ipending field in mdglobaldata is revoked, which is only
    used by slow interrupt vector handler.
    
    ithread_fast_handler()'s invoking convetion is changed:
    - ithead_fast_handler() must be called with critical section being held
    - Callers of ithead_fast_handler() no longer bump gd_intr_nesting_level
