Yeah sorry, I should have said "implementations of MSR_LE on 32-bit cpus". We can always add a 32-bit version in future if we need to, but we can't remove it once it's there, so for now we won't do it on 32-bit. cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
