ppc: Properly tag the translation cache based on MMU mode
We used to always flush the TLB when changing relocation mode in MSR:IR and MSR:DR (ie. MMU on/off for Instructions and Data). We don't anymore since we have split mmu_idx for instruction and data. However, since we hard code the mmu_idx in the translated code, we now need to also make sure MSR:IR and MSR:DR are part of the hflags used to tag translated code, so that we use different translated code for different MMU settings. Darwin gets hurt by this problem. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
