SVN rev 203000 on 2010-01-26 03:39:10Z by neel
Install the XTLB exception handler for Sibyte processors.
This is a workaround for the fact that the CFE is compiled as a 64-bit
application and therefore sets the SR_KX bit every time we call into
it (for e.g. console).
A TLB miss for any address above 0xc0000000 with the SR_KX bit set will
end up at the XTLB exception vector. We workaround this by copying the
standard TLB handler at the XTLB exception vector.
