Modified Files:
        src/sys/arch/x86/x86: intr.c

Log Message:
Add interrupt stack "red zones".  Reserve and unmap the virtual
pages immediately above and below the x86 interrupt stack so that
both an overgrown interrupt stack and other faults produce a page
fault trap.  Condition this on the historical option NOREDZONE,
for now.
