since "MIPS: Calculate proper ebase value for 64-bit kernels" my mips
toy did not boot anymore.
Before that commit we always touched xkphys/shared as ebase and computed
xphsys/unchached for that area. After that commit ebase become 32bit
compat address and convert does not work anymore. So I guess now want to
touch the 32bit compat unmapped & uncached area for this. CKSEG1ADDR
does just in 32bit and 64bit.
