Modified files:
sys/amd64/amd64 trap.c
sys/i386/i386 trap.c
Log:
If the trap number stored in the trapframe is corrupted into a negative
value, then we would use a negative index into the trap_msg[] array
resulting in a nested page fault. Make the 'type' variable holding the
trap number unsigned to avoid this.
