Restore a load from KSEG1 done as a workaround for an R4600 v2 erratum, dropped with 211be16de99a7424e66c0b6c0d00e2c970508ac2. Signed-off-by: Maciej W. Rozycki <macro@xxxxxxxxxxxxxx> --- Thiemo, It reverts your change of Sep 1st, 2005; given the way the code is written, I am assuming the change was accidental, correct? At the moment the load never happens. Ralf, please apply.
