Module Name:    src

Modified Files:
        src/sys/arch/arm/arm32: fault.c

Log Message:
Since data_abort_handler() may have to decode the instruction at tf->tf_pc
to determine if a fault is read or write, make sure tf->tf_pc is 32-bit
aligned before dereferencing it.

Otherwise, deliver an illegal instruction signal to the process. We don't
support execution of Thumb code at this time.
