    Subject[PATCH v1 0/4] Support register names from all architectures
    Date
    The following changeset applies some corrections to the way system
    registers are processed and presented when reading perf.data files using
    the various perf tools.

    The commit message from [4/4] shows how register names aren't correctly
    presented when performing x-arch analysis of perf.data files (i.e.
    recording in one arch, then reading the file from a different arch).

    Please let me know if there are any concerns with this approach, or if
    any improvements can be made for subsequent re-rolls of the changeset.

    - [PATCH 1/4] Fixes a potential out-of-bounds access when reading the
    values of the registers in the perf.data file.
    - [PATCH 2/4] Modifies one of the callbacks in "struct scripting_ops"
    so that the python version can obtain the correct register names.
    - [PATCH 3/4] Adds header files with the register indices and names
    from all architectures, which are used by the next patch.
    - [PATCH 4/4] Refactors the function "perf_reg_name" so that it can
    support registers from all architectures, not just the local one.

    Thanks,
    German
