All these new register sets can be accessed through PTRACE_GETREGSET /SETREGSET requests with the new NT_PPC_* core note types added in the previous patch. PowerPC already has some register specific ptrace requests, so thought of adding some new requests for transactional memory purpose. But yes these are redundant and can be dropped. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
