MIPS: Use CKSEG1ADDR for uncached handler
"MIPS: Calculate proper ebase value for 64-bit kernels"
9af43ea080dd5d6c7b34f38261780e5dd43537bc (lmo) rsp.
f6be75d03c8870be91e6e2a195648ece04b6bb16 (kernel.org) broke some 64-bit
MIPS systems.
Before this we were using XKPHYS/cached as ebase and computed the uncached
xphsys/unchached address for that area. After that commit ebase became a
32-bit compat address and convert does not work anymore. We now should use
CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.
