Peter Grehan ebc2aa7496 Temporary band-aid to fix hang when a process exec's Altivec instructions. 
trap_subr.S:  declare a stub for the a-unavailable trap
              that does an absolute jump to the vector-assist trap.
              This is due to the fact that the vec-unavail trap
              doesn't start at a 256-byte boundary, so the trick of
              masking the bottom 8 bits of the link register to identify
              the interrupt doesn't work, so let the vec-assist
              case handle Altivec-disabled for the time being.

              Note that this will be fixed in the future with a much
              smaller vector code-stub (< 16 bytes) that will allow
              use of strange vector offsets that are also present in
              4xx processors, and also allow smaller differences in
              vector codepaths on the G5.

trap.c:       Treat altivec-unavailable/assist process traps as SIGILL.
              Not quite correct, since altivec-assist should really be a panic,
              but it is fine for the moment due to the above measure.

machdep.c     Install the stub code for the altivec-unavailable trap, and
              the standard trap code at the altivec-assist.
