H A D | sb_machdep.c | diff 203000 Tue Jan 26 01:51:39 MST 2010 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.
