Can you explain this more. right now we generate vsid as below vsid_scramble(ea >> SID_SHIFT, 256M) for kernel vsid_scramble((context << USER_ESID_BITS) | (ea >> SID_SHIFT), 256M); for user what changes are you suggesting ? -aneesh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
