I wouldn't think it's a big deal, but then, the 32-bit hash code has to also update _PAGE_HASHPTE etc... overall I wouldn't touch it for now. However, 8xx should instead look at what I do in recent versions of head_44x.S or what Kumar did in head_fsl_booke.S Cheers, Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
