  Modified files:
    sys/i386/isa         intr_machdep.c 
  Log:
  Fixed a longstanding scheduling bug.  ASTs and softclock interrupts were
  not masked during handling of shared PCI interrupts.  This resulted in
  ASTs sometimes being discarded and softclock interrupts sometimes being
  handled prematurely (sometimes = quite often on systems with shared PCI
  interrupts, never on other systems).
