[PATCH] i386: don't blindly enable interrupts in die()
Rather than blindly re-enabling interrupts in die(), save their state
upon entry and then restore that state.
If the kernel is in really bad condition and faults with interrupts disabled,
re-enabling them in die() may cause even more trouble, implying more chances
of data corruption.
